Today's computers typically come with a hard disk that can contain anywhere from billions to trillions of bytes of storage.
A hard disk is actually a set of stacked disks, like phonograph records.
Each disk has data recorded electromagnetically in concentric circles, or tracks, on the disk.
A head, similar to a phonograph arm but in a relatively fixed position, writes or reads the information on the tracks.
Two heads, one on each side of a disk, read or write the data as the disk spins.
Each read or write operation requires that data be located, an operation called a seek.
Data already in ahowever, will be located more quickly.
Most laptop and desktop PCs use hard disks that fall between 5,400 rpm and 7,200 rpm, while hard disks at higher rpm can be found in high-end workstations and enterprise servers.
Disk access time is measured in milliseconds.
Although the physical location of data can be identified with cylinder, track and sector locations, these are actually mapped to a logical block address that works with the larger address range on hard disks.
Hard disks remain a popular data storage option for consumers and enterprises, in spite of the growing popularity and rapidly lowering cost of nonvolatile solid-state flash memory in the form of solid-state drives.
SSDs fit into the same external and internal drive bays as their HDD counterparts.
SSDs may be much faster, more durable and draw less power than hard disks, but they are also more expensive.
SSDs are considered a better fit for applications that demand high performance, while HDDs are more often used for high-capacity use cases.
The company then shipped the first commercial hard disk-based computer, the 5 MB IBM 305 random access method of accounting and control in 1956.
The storage component of the IBM 305 RAMAC was called IBM 350 Disk Storage.
It was nevertheless a huge jump forward in computer storage technology, which had mostly been reliant on.
The movable read and write heads of RAMAC enabled semirandom access to data for the first time.
IBM continued to lead the development of hard disk technology over the next couple of decades.
In 1961, the drive heads of the IBM 1301 Disk Storage Unit floated on a thin layer of air, which kept the heads and platters closer for an increase in storage density.
A couple of years later, IBM introduced the first removable hard drive, the 1311.
Its first disk pack, the IBM 1316, consisted of six 14-inch platters and 2.
Memorex introduced the first IBM-compatible hard disk in 1968.
In 1970, the first hard drives with error correction appeared, and Western Digital at the time named General Digital Corporation was established.
In 1973, IBM released the 3340 -- known as the "Winchester" -- the first sealed hard drive with low-mass heads and lubricated.
The first patent for redundant array of independent disks RAID technology was filed in 1978, and in 1979, a group headed by Al Shugart, who helped develop RAMAC decades earlier, founded Seagate Technology Corp.
That was also the year IBM rolled out its Piccolo drive, which used eight disks to store 64 MB, and the IBM 3370, the first HDD with a head.
This was the same year Seagate introduced the first 5.
Scottish company Rodime produced a 3.
Three years later, the Small Computer System Interface standard came along.
In 1988, PrairieTek shrank the hard drive to 2.
With the dawn of the 1990s came IBM's 0663 Corsair drive.
Storing up to 1 GB of data on 8.
Drives continued to shrink, with the first 1.
Western Digital developed the Enhanced IDE hard drive interface, breaking the 528 MB throughput barrier, in 1994.
By 1996, IBM was storing 1 billion per square inch on a platter, and Seagate's Cheetah family became the first 10,000 rpm HDDs.
In 1997, IBM rolled out the 3.
The company's Microdrive, released the next year, stored 340 MB on a single 1-inch disk platter.
In 2000, Maxtor bought competitor Quantum's hard drive business, and Seagate hit 15,000 rpm with its Cheetah X15 HDD.
Seagate achieved another milestone by demonstrating a perpendicular magnetic recording areal density of 100 Gb per square inch that same year.
Hitachi bought IBM's data storage business in 2003, Seagate produced the first computer bus interface and Western Digital made the first 10,000 rpm SATA hard drive, the 37 GB Raptor.
In 2004, Toshiba released the first 0.
In 2006, Seagate acquired Maxtor, further consolidating the hard drive market.
Drive capacities continued to skyrocket from there.
Capacity By the end of the 2000s, Seagate and Western Digital had released the first 3 TB HDDs, with those companies and Toshiba producing the first 4 TB drives early the next decade.
In 2013, Seagate had a 5 TB HDD, while HGST a Western Digital subsidiary shipped a 6 TB helium-filled hard disk.
That means drives filled with helium run cooler and faster and can have higher storage densities.
In addition, a helium-filled hard disk enables manufacturers to put seven platters in the same space required for five platters in conventional hard drives.
Look inside an HGST helium hard disk in this video from HddSurgery.
Also in 2013, Seagate introduced hard disks using shingled magnetic recording technology to further overcome the physical limitations of conventional drives.
SMR layers magnetic tracks on each disk instead hard drive slot definition and function placing them parallel to each other as in conventional hard disks, thereby increasing storage density.
The tracks overlap like shingles on a roof, hence the name of the technology.
Today, thanks in part to the development of helium-based HDDs and SMR technology, hard disk capacities have grown to 10 TB, 12 TB, 14 TB and 16 TB.
Parts of a hard drive A hard drive consists of several major components inside its casing.
Hard disks include one or more aluminum, glass or ceramic platters made of material with a thin magnetic surface, or media layer, to store data.
Platters store and organize data in specific structures -- tracks, sectors and clusters -- on this media layer, which is only a few millionths of an inch thick.
A superthin protective and lubricating protective layer above the magnetic media guards against accidental damage and contamination by foreign material, like dust.
Hard disk components The spindle rotates the platters as needed and holds them in position.
The rpm of the spindle determine how fast data is written and read.
Joanne Larson, an engineer slot and go Seagate Technology, demonstrates how a hard disk works.
An intelligent check this out, or logic board, tells the actuator motor what to do.
The drive's internals, also known as the head assembly, are mounted securely hard drive slot definition and function the casing and then usually covered with aluminum.
The form factor of an HDD is the size and shape of this enclosure.
The HDD form factor governs its compatibility with the drive bays of desktop and portable computers, servers, storage enclosures, storage arrays or any consumer product that uses a hard disk, such as a digital video recorder DVR.
Industry standards dictate the geometry ofwhich includes the length, width and height of the HDD, in addition to the orientation and position of the host interface connector.
Common enterprise-class HDD form factors are 2.
While enterprise-class HDD enclosures typically have standard lengths and widths, height can vary -- up to 15 mm and 26.
Hard disk destruction services Just because data is hard drive slot definition and function and is no longer accessible to https://free-money-games.website/and-slots/pachinko-and-slot-japan.html application or operating system OS that created it, that doesn't mean the information isn't available on a hard disk.
Formatting a drive doesn't always destroy data bits, neither does overwriting data repeatedly with other data.
Specialized programs called hard drive shredders overwrite data and are intended to click that data irretrievable.
There are experts who say original data may still be recoverable after using a hard drive shredder, even if the overwriting process used by these programs occurs hundreds hard drive slot definition and function times over.
Drilling holes through the hard disk won't necessarily do the trick either, as some tracks will remain unaffected.
Pulverizing the hard disk assembly ensures that all the data on a hard disk is destroyed.
The only way to ensure that all the data on a hard disk is destroyed is to pulverize the whole assembly.
For a fee, companies such as ProShred and Securis will securely pick up and transport a hard disk and shred it much like a wood chipper disposes of brush and tree limbs.
They will also certify the data has been destroyed in a manner that meets proper compliance and environmental regulations.
Common hard disk errors Hard disks can fail for all sorts of reasons.
However, failures generally fall into six broad categories.
If a hard disk powers on but can't read and write data or boot, it is likely that one or more of its components has suffered an electrical failure.
Mechanical failure can be caused by wear and tear, as well as by a hard impact, such as dropping an external hard drive slot definition and function disk or the computer that houses an internal hard disk.
Logical failure results when the hard disk's software is compromised or ceases to run properly.
All sorts of data corruption -- such as corrupted files, malware and viruses, the improper closing of an application or shutting down of a computer, human error or accidental deletion of files critical to hard disk functionality -- can lead to a logical failure.
The effects of a logical failure vary from recurrent crashes to constant freezing and disk errors, the disappearance of data, inaccessible files and more.
Bad sector failure can occur when there is a misalignment of the magnetic media on a hard disk's rotating platter, resulting in a specific area s on the platter becoming inaccessible.
Bad sectors are commonplace and often limited when they occur.
Over time, however, the number of bad sectors can increase, eventually leading to a crash, inaccessible files or the hanging or lagging of the operation of a hard disk.
Firmware failure happens when the software that performs the maintenance tasks on a drive and enables the hard disk to communicate with a computer becomes corrupted or stops working properly.
This type of failure can lead to the disk freezing during bootup or the computer a hard disk is connected to not recognizing or misidentifying it.
Multiple unknown failures that accumulate over time can also occur.
It might also lead to a logical failure, resulting in several bad sectors developing on the hard disk platters.
Related Terms A race condition is an undesirable situation that occurs read more a device or system attempts to perform two or more operations at.

The motherboard is one of the most important parts of the PC, but as a tech enthusiast, you probably already know that.
What you hard drive slot definition and function not know, though, is the role played by each chip, port or slot present on a motherboard.
The role of the motherboard is to allow Paco and Peppers slot machine these components to communicate with each other.
Considering the fact that all the other components are installed on the motherboard or connected to it, it is safe to say that the motherboard is the central piece of a PC, the component that brings it all together.
Processor Socket The processor socket is the central piece of a link, usually being located near the center of the motherboard.
Power Connectors No computer component can operate without power, and a motherboard is no exception.
The power connector, commonly a 20 or 24-pin connector, can be situated either near the right edge of the motherboard, or somewhere close to the processor socket on older motherboards.
Newer motherboards have an additional 4-pin or 8-pin connector near the processor, used to supply additional power directly to the processor.
The number of slots can vary, depending on motherboard, from 2, in low-end motherboards, all the way up to 8 memory slots, on high-end and gaming motherboards.
It is important to pay close attention to the type of memory a motherboard supports, in order to buy the appropriate memory modules.
Newer motherboards support DDR3 memory, the current industry standard memory architecture, but motherboards with DDR2 memory slots and even DDR1 memory slots are still present on the market.
An interesting aspect is that there are some older motherboard models that supported different types of memory, and usually come with two DDR1 memory slots and 2 DDR2 memory slots, or two DDR2 slots and two DDR3 slots.
These motherboards were great options for people that wanted to upgrade a motherboard without having to upgrade all the other components as well.
The number of memory slots should be an important criterion to take into account when choosing a motherboard, as it will determine the maximum amount of memory you can install.
You may plan to or — do you really want to be limited by your motherboard in the process?
Coming in the form of a PCI-Express slot on newer motherboards or AGP on older ones, the video card slot is situated right below the processor.
At the opposite pole, high-end gaming motherboards come with multiple video card slots, allowing the installation of multiple video cards in a SLI or CrossFire configuration.
Expansion Slots Expansions have the role of letting you install additional components to enhance or expand the functionality of your PC.
You can install a TV tuner, a video capture card, a better soundcard, etc.
These ports are located under the video card slot, and come in the form of PCI slots on older motherboards or a scaled-down version of PCI-Express slots on newer motherboards.
Some motherboards come with both types of expansion slots.
The number of slots is usually dependent on the format of the motherboard — larger motherboards full ATX have more, while smaller formats micro-ATX have fewer, if any.
IDE and SATA Ports IDE and SATA ports are used to provide connectivity for the storage devices and optical drives.
It is not uncommon for manufacturers to include SATA ports of different revisions, such as two SATA2 ports and two SATA3 ports.
Considering the fact that most optical drives on the market come with a SATA connector, and these devices are not bandwidth-hungry, using a SATA2 port for an optical drive is perfectly acceptable.
Since the BIOS code is stored on a memory chip that needs constant power to function, a battery is also present to keep the chip powered when the computer is unplugged.
This metal component is actually a heatsink, and its role is to provide thermal protection for the Northbridge — one of the most important components of a motherboard.
The northbridge is responsible for coordinating the data flow between the memory, the video card and the processor.
A secondary chip, known as Southbridge, has a similar function, coordinating the data flow between the processor and peripherals such as sound cards or network cards.
Front Panel Connectors, USB Headers and Audio Header The front panel connector is where all the elements present on the front of your case are connected.
Power button, reset button, power led, audio connectors and USB connectors — they are all connected to the front panel or the corresponding headers.
Rear Connectors These connectors are the bridge between the outside of your computer and the inside.
The name is a bit misleading, as the connectors are actually located on the left edge of the motherboard; however, since these connectors are accessible from the outside, the name hard drive slot definition and function implies where they are accessible from — the rear of the PC case.
External peripherals hard drive slot definition and function as keyboard, mouse, monitor, speakers and so on are all connected via these connectors.
So there you have it, the parts of the motherboard and their functions, explained.
Now that you know how to choose your motherboard and https://free-money-games.website/and-slots/bingo-and-slots-no-deposit-bonus.html your dream PC, you might want to The article provides here detailed outline of two of the most popular operating systems, Linux and Windows, allowing you to determine which will suite your needs better.

The platters are paired withusually arranged on a moving arm, which read and write data to the platter surfaces.
Data is accessed in a manner, meaning that individual of data can be stored or retrieved in any order and not only.
HDDs are a type ofretaining stored data even when powered off.
Introduced by in 1956, HDDs became the dominant device for by the early 1960s.
Continuously improved, HDDs have maintained this position into the modern era of and.
More than 224 companies havethough after extensive industry consolidation most units are manufactured by, and.
HDDs dominate the volume of storage produced per year for.
Though production is growing slowly, sales revenues and unit shipments are declining because SSDs have higher data-transfer rates, higher areal storage density, better reliability, and much lower latency and access times.
The revenues for SSDs, most of which use NAND, slightly exceed those for HDDs.
Though SSDs have nearly 10 times higher cost per bit, they are replacing HDDs in applications where speed, power consumption, small size, and durability are important.
The primary characteristics of an HDD are its capacity and.
Typically, some of an HDD's capacity is unavailable to the user because it is used by the and the computerand possibly inbuilt redundancy for and recovery.
Also there is confusion regarding storage capacity, since capacities are stated in decimal Gigabytes powers of 10 by HDD manufacturers, whereas some operating systems report capacities in binary Gibibytes, which results in a smaller number than advertised.
Performance is specified by the time required to move the heads to a track or cylinder average access time adding the time it takes for the desired sector to move under the head averagewhich is a function of the physical inand finally the speed at which the data is transmitted data rate.
The two most common for modern HDDs are 3.
HDDs are connected to systems by standard cables such as Parallel ATASerial ATAor SAS cables.

It was approximately the size of two medium-sized refrigerators and stored five million six-bit characters 3.
Motion of the head array depended upon a binary adder system of hydraulic actuators which assured repeatable positioning.
The 1301 cabinet was about the size of three home refrigerators placed side by side, storing the equivalent of about 21 million eight-bit bytes.
Access time was about a quarter of a second.
Also in 1962, IBM introduced the disk drive, which was about the size of a washing machine and stored two million characters on a removable.
Users could buy additional packs and interchange them as needed, much like reels of.
Later models of removable pack drives, from IBM and others, became the norm in most computer installations and reached capacities of 300 megabytes by the early 1980s.
Non-removable HDDs were called "fixed disk" drives.
Some high-performance HDDs were manufactured with one head per track e.
Known as fixed-head or head-per-track disk drives they were very expensive and are no longer in production.
In 1973, IBM introduced a new type of HDD code-named "".
Its primary distinguishing feature was that the disk heads were not withdrawn completely from the stack of disk platters when the drive was powered down.
Instead, the heads were allowed to "land" on a special area of the disk surface upon spin-down, "taking off" again when the disk was later powered on.
This greatly reduced the cost of the head actuator mechanism, but precluded removing just the disks from the drive as was done with the disk packs of the day.
Instead, the first models of "Winchester technology" drives featured a removable disk module, which included both the disk pack and the head assembly, leaving the actuator motor in the drive upon removal.
Later "Winchester" drives abandoned the removable media concept and returned to non-removable platters.
Like the first removable pack drive, the first "Winchester" drives used platters 14 inches 360 mm in diameter.
A few years later, designers were exploring the possibility that physically smaller platters might offer advantages.
The latter were primarily intended for the then-fledgling personal computer PC market.
As the 1980s began, HDDs were a rare and very expensive additional feature in PCs, but by the late 1980s their cost had been reduced to the point where they were standard on all but the cheapest computers.
Most HDDs in the early 1980s were sold to PC end users as an external, add-on subsystem.
The subsystem was not sold under the drive manufacturer's name but under the subsystem manufacturer's name such as andor under the PC system manufacturer's name such as the.

Older compact Macintosh computers did not have user-accessible hard drive bays indeed, the, and did not feature a hard drive bay at allso on those models external SCSI disks were the only reasonable option for expanding upon any internal storage.
Driven by ever increasingHDDs have continuously improved; a few highlights are listed in the table above.
Market applications expanded through the 2000s, from the of the late 1950s to most applications including computers and consumer applications such as storage of entertainment content.

Relatively new technologies like HDMR, HAMR and MAMR, Bit patterned media and dual independent actuator arms increase the speed and capacity of HDDs and are expected to make HDDs more competitive with SSDs.
The damaged the manufacturing plants and impacted hard disk drive cost adversely between hard drive slot definition and function and 2013.
Sequential changes in the direction of magnetization represent binary data.
The data is read from the disk by detecting the transitions in magnetization.
User data is encoded using an encoding scheme, such as encoding, which determines how the data is represented by the magnetic transitions.
A typical HDD design consists of a spindle that holds flat circular disks, calledwhich hold the recorded data.
The platters are made from a non-magnetic material, usually aluminum alloy, glass, or ceramic.
They are coated with a shallow layer of magnetic material typically 10—20 in depth, with an outer layer of carbon for protection.
For reference, a standard piece of copy paper is 0.
Recording of single magnetisations of bits on a 200 MB HDD-platter recording made visible using CMOS-MagView.
The first HDDs spun at 1,200 rpm and, for many years, 3,600 rpm was the norm.
As of December 2013, the platters in most consumer-grade HDDs spin at either 5,400 RPM or 7,200 RPM.
Information is written to and read from a platter as it rotates past devices called that are positioned to operate very close to the magnetic surface, with their often in the range of tens of nanometers.
The read-and-write head is used to detect and modify the magnetization of the material passing immediately under it.
In modern drives, there is one head for each magnetic platter surface on the spindle, mounted on a common arm.
An actuator arm or access arm moves the heads on an arc roughly radially across the platters as they spin, allowing each head to access almost the entire surface of the platter as it spins.
The arm is moved using a actuator or in some older designs a.
Early hard disk drives wrote data at some constant bits per second, resulting in all tracks having the same amount of data per track but modern drives since the 1990s use — increasing the write speed from inner to outer zone and thereby storing more data per track in the outer zones.
To counter this, the platters are coated with two parallel magnetic layers, separated by a three-atom layer of the non-magnetic elementand the two layers are magnetized in opposite orientation, thus reinforcing each other.
Another technology used to overcome thermal effects to allow greater recording densities isfirst shipped in 2005, and as of 2007 used in certain HDDs.
In 2004, a new concept was introduced to allow further increase of the data density in magnetic recording: the use of recording media consisting of coupled soft and hard magnetic layers.
So-called magnetic storage technology, also known as exchange coupled composite media, allows good writability due to the write-assist nature of the soft layer.
However, the thermal stability is determined only by the hardest layer and not influenced by the soft layer.
The disk motor has an external rotor attached to the disks; the stator windings are fixed in place.
Opposite the actuator at the end of the head support arm is the read-write head; thin printed-circuit cables connect the read-write heads to electronics mounted at the pivot of the actuator.
The head support arm is very light, but also stiff; in modern drives, acceleration at the head reaches 550.
Close-up of a singleshowing the side facing the platter The actuator is a and motor that swings the heads to the desired position.
A metal plate supports a squat NIB high-flux.
Beneath this plate is the moving coil, often referred to as the by analogy to the coil inwhich is attached to the actuator hub, and beneath that is a second NIB magnet, mounted on the bottom plate of click to see more motor some drives have only one magnet.
The voice coil itself is shaped rather like an arrowhead, and made of doubly coated copper.
The inner layer is insulation, and the outer is thermoplastic, which bonds the coil together after it is wound on a form, making it self-supporting.
The portions of the coil along the two sides of the arrowhead which point to the actuator bearing center then interact with the of the fixed magnet.
Current flowing radially outward along one side of the arrowhead and radially inward on the other produces the.
If the magnetic field were uniform, each side would generate opposing forces that would cancel each other out.
Therefore, the surface of the magnet is half north pole and half south pole, with the radial dividing line in the middle, causing the two sides of the coil to see opposite magnetic fields and produce forces that add instead of canceling.
Currents along the top and bottom of the coil produce radial forces that do not rotate the head.
The HDD's electronics control the movement of the actuator and the rotation of the disk, and perform reads and writes on demand from the.
Feedback of the drive electronics is accomplished by means of special segments of the disk dedicated to feedback.
These are either complete concentric circles in the case of dedicated servo technologyor segments interspersed with real data in the case of embedded servo technology.
The servo feedback optimizes the signal to noise ratio of the GMR sensors by adjusting the voice-coil of the actuated arm.
The spinning of the disk also uses a servo motor.
Modern disk firmware is capable of scheduling reads and writes efficiently on the platter surfaces and remapping sectors of the media which have failed.
These techniques store extra bits, determined by mathematical formulas, for each block of data; the extra bits allow many errors to be corrected invisibly.
The extra bits themselves take up space on the HDD, but allow higher recording densities to hard drive slot definition and function employed without causing uncorrectable errors, resulting in much larger storage capacity.
For example, a typical 1 hard disk with 512-byte sectors provides additional capacity of about 93 for the data.
In the newest drives, as of 2009, LDPC were supplanting Reed—Solomon; LDPC codes enable performance close to the and thus provide the highest storage density available.
Typical hard disk drives attempt to "remap" the data in a physical sector that is failing to a spare physical sector provided by the drive's "spare sector pool" also called "reserve pool"while relying on the ECC to recover stored data while the number of errors in a bad sector is still low enough.
The Self-Monitoring, Analysis and Reporting Technology feature counts the total number of errors in the entire HDD fixed by ECC although not on all hard drives as the related S.
T attributes "Hardware ECC Recovered" and "Soft ECC Correction" are not consistently supportedand the total number of performed sector remappings, as the occurrence of many such errors may predict an.
The "No-ID Format", developed by IBM in the mid-1990s, contains information about which sectors are bad and where remapped sectors have been located.
Only a tiny fraction of the detected errors end up as not correctable.
Within a given manufacturers model the uncorrected bit error rate is typically the same regardless of capacity of the drive.
The worst type of errors are which are errors undetected by the disk firmware or the host operating system; some of these errors may be caused by hard hard drive slot definition and function drive malfunctions while others originate elsewhere in the connection between the drive and the host.
Speaking in 1997, called the increase "flabbergasting", while observing later that growth cannot continue forever.
The rate of advancement for areal density slowed to 10% per year during 2010—2016, and there was difficulty in migrating from perpendicular recording to newer technologies.
As bit cell size decreases, more data can be put onto a single drive platter.
Since the mid-2000s areal density progress has increasingly been challenged by a trilemma involving grain size, grain magnetic strength and ability of the head to write.
In order to maintain acceptable signal to noise smaller grains are required; smaller grains may self-reverse unless their magnetic strength is increased, but known write head materials are unable to generate a strong enough magnetic field sufficient to write the medium in the increasingly-smaller space taken by grains.
Several new magnetic storage technologies are being developed to overcome or at least abate this trilemma and thereby maintain the competitiveness of HDDs with respect to products such as —based SSDs.
In 2013, introduced SMRintended as something of a "stopgap" technology between PMR and Seagate's intended successor HAMRSMR utilises overlapping tracks for increased data density, at the cost of design complexity and lower data access speeds particularly write speeds and 4k speeds.
By contrast, competitor focused on developing ways to seal -filled drives, the aim being to reduce and effects, and fit more platters of a traditional design into the same enclosure space, by filling the drives with helium which is a notoriously difficult gas to prevent escaping instead of the usual filtered air.
The rate of areal density growth has dropped below the historical Moore's law rate of 40% per year, and the deceleration is expected to persist through at least 2020.
Depending upon assumptions on feasibility and timing of these technologies, the median forecast by industry observers and analysts for 2020 and beyond for areal density growth is 20% per year with a range of 10—30%.
Seagate began sampling HAMR HDDs in 2018.
Also the difference in capacity reported in SI decimal prefixed units vs.
This information is available from the manufacturer's product specification, and from the drive itself through use of operating system functions that invoke low-level drive commands.
The gross capacity of older HDDs is calculated as the product of the number of per recording zone, the number of bytes per sector most commonly 512and the count of of the drive.
In modern HDDs, spare capacity for defect management is not included in the published capacity; however, in many early HDDs a certain number of sectors were reserved as spares, thereby reducing the capacity available to the operating system.
For subsystems, data integrity and fault-tolerance requirements also reduce the realized capacity.
RAID subsystems are multiple drives that appear to be one drive or more drives to the user, but provide fault tolerance.
Most RAID vendors use to improve data integrity at the block level.
Some vendors design systems using HDDs with sectors rome and glory slot free play pity 520 bytes to contain 512 bytes of user data and eight checksum bytes, or by using separate 512-byte sectors for the checksum data.
Some systems may use hidden for system recovery, reducing the capacity available to the end user.
Each block is delimited by markers identifying its start and end, error detecting and correcting information, and space between blocks to allow for minor timing variations.
These blocks often contained 512 bytes of usable data, but other sizes have been used.
As drive density increased, an initiative known as extended the block size to 4096 bytes of usable data, with a resulting significant reduction in the amount of disk space used for block headers, error checking data, and spacing.
The process of initializing these logical blocks on the physical disk platters is called low-level formatting, which is usually performed at the factory and is not normally changed in the field.
High-level formatting writes data structures used by the operating system to organize data files on the disk.
This includes writing and structures into selected logical blocks.
For example, some of the disk space will be used to hold a directory of disk file names and a list of logical blocks associated with a particular file.
Examples of partition mapping scheme include MBR and GPT.
Examples of data structures stored on disk to retrieve files include the FAT in the file system and in many file systems, as well as other operating system data structures also known as.
As a consequence, not all the space on an HDD is available for user files, but this system overhead is usually small compared with user data.
This practice dates back to the early days of computing; by the 1970s, "million", "mega" and "M" were consistently used in the decimal sense for drive capacity.
However, capacities of are quoted using a of the prefixes, i.
Software reports hard disk drive or memory capacity in different forms using either decimal or binary prefixes.
The family of operating systems uses the binary convention when reporting storage capacity, so an HDD offered by its manufacturer as a 1 TB drive is reported by these operating systems as a 931 GB HDD.
The default behavior of the df on Linux is to report the HDD capacity as a number of 1024-byte units.
The difference between the decimal and binary prefix interpretation caused some consumer confusion and led to class action suits.
The plaintiffs argued that the use of decimal prefixes effectively misled consumers while the defendants denied any wrongdoing or liability, asserting that their marketing and advertising complied in all respects with the law and that no class member sustained any damages or injuries.
In 1962, introduced its disk, which used six 14-inch nominal size platters in a removable pack and was roughly the size of a washing machine.
This became a standard platter size for many years, used also by other manufacturers.
The used platters of the same size in an eleven-high pack and introduced the "drive in a drawer" layout.
Into the 1970s HDDs were offered in standalone cabinets of varying dimensions containing from one to four HDDs.
Beginning in the late 1960s drives were offered that fit entirely into a chassis that would mount in a.
Digital's and RL01 were early examples using single 14-inch platters in removable packs, the hard drive slot definition and function drive fitting in a 10.
In the mid-to-late 1980s the similarly sizedwhich used coincidentally 10.
With increasing sales of microcomputers having built inHDDs that would fit to the FDD mountings became desirable.
Starting with the HDD Form factors, initially followed those of 8-inch, 5½-inch, and 3½-inch floppy disk drives.
Although referred to by these nominal sizes, the actual sizes for those three drives respectively are 9.
Because there were no smaller floppy disk drives, smaller HDD form factors developed from product offerings or industry standards.
As of 20192½-inch and 3½-inch hard disks are the most popular sizes.
By 2009, all manufacturers had discontinued the development of new products for the 1.
While nominal sizes are in inches, actual dimensions are specified in millimeters.
The first HDD had an average seek time of about 600 ms.
Some early PC drives used a to move the heads, and as a result had seek times as slow as 80—120 ms, but this was quickly improved by type actuation in the 1980s, reducing seek times to around 20 ms.
Seek time has continued to improve slowly over time.
The fastest server drives today have a seek time around 4 ms.
The average is strictly the time to do all possible seeks divided by the number of all possible seeks, but in practice is determined by statistical methods or simply approximated as the time of a seek over one-third of the number of tracks.
Rotational latency is incurred because the desired may not be directly under the head when data transfer is requested.
Average rotational latency is shown in the table, based on the statistical relation that the average latency is one-half the rotational period.
The or data transfer rate once the head is in the right position creates delay which is a function of the number of blocks transferred; typically relatively small, but can be quite long with the transfer of large contiguous files.
Delay may also occur if the drive disks are stopped difference edge flaps slots and slats save energy.
Some computer operating systems perform defragmentation automatically.
Although automatic defragmentation is intended to reduce access delays, performance will be temporarily reduced while the procedure is in progress.
Time to access data can be improved by increasing rotational speed thus reducing latency or by reducing the time spent seeking.
Increasing areal density increases by increasing data rate and by increasing the amount of data under a set of heads, thereby potentially reducing seek activity for a given amount of data.
The time to jack and the beanstalk slot game data has not kept up with throughput increases, which themselves have not kept up with growth in bit density and storage capacity.
This rate depends on the track location; the rate is higher for data on the outer tracks where there are more data sectors per rotation and lower toward the inner tracks where there are fewer data sectors per rotation ; and is generally somewhat higher for 10,000-rpm drives.
A current widely used standard for the "buffer-to-computer" interface is 3.
Transfer rate can be influenced by and the layout of the files.
HDD data transfer rate depends upon the rotational speed of the platters and the data recording density.
Because heat and vibration limit rotational speed, advancing density becomes the main method to improve sequential transfer rates.
Higher speeds require a more powerful spindle motor, which creates more heat.
While areal density advances by increasing both the number of tracks across the disk and the number of sectors per track, only the latter increases the data transfer rate for a given rpm.
Since data transfer rate performance tracks only one of the two components of areal density, its performance improves at a lower rate.
The has a quality-adjusted for large-scale enterprise storage systems including three or more enterprise HDDs and associated controllers, racks and cables.
Some drives, especially external portable drives, useor.
Current drives present a consistent interface to the rest of the computer, independent of the data encoding scheme used internally, and independent of the physical number of disks and heads within the drive.
Typically a in the electronics inside the drive takes visit web page raw analog voltages from the read head and uses and to decode the data, then sends that data out the standard interface.
That DSP learn more here watches the error rate detected byand performs remapping, data collection forand other internal tasks.
Each drive also has an additional power cable, usually direct to the power supply unit.
Older interfaces had separate cables for data signals and for drive control signals.
The length limit of the data cable allows for external SCSI devices.
The data cable was originally 40-conductor, but later higher speed requirements led to an mode using an 80-conductor cable with additional wires to reduce at high speed.
By directly transferring data between memory and disk, DMA eliminates the need for the CPU to copy byte per byte, therefore allowing it to process other tasks while the data transfer occurs.
It is a please click for source protocol.
In disk drives usually the FC-AL connection topology is used.
FC has much broader usage than mere disk interfaces, and it hard drive slot definition and function the cornerstone of SANs.
Recently other protocols for this field, like and have been developed as well.
Confusingly, drives usually use copper twisted-pair cables for Fibre Channel, not fibre optics.
The latter are traditionally reserved for larger devices, such as servers or.
The SAS is a new generation serial communication protocol for devices designed to allow for much higher speed data transfers and is compatible with SATA.
SAS uses a mechanically identical data and power connector to standard 3.
SAS uses serial communication instead of the parallel method found in traditional SCSI devices but still uses SCSI commands.
The SATA data cable has one data pair for differential transmission of data to the device, and one pair for differential receiving from the device, just like.
That requires that data be transmitted serially.
A similar system is used in, and differential.
SATA I to III are designed to be compatible with, and use, a subset of SAS commands, and compatible interfaces.
However they cannot be connected the other way round - a SATA controller cannot be connected to a SAS drive.
See also: Due to the extremely close spacing between the heads and the disk surface, HDDs are vulnerable to being damaged by a — a in which the head scrapes across the platter surface, often grinding away the thin magnetic film and causing data loss.
Head crashes can be caused by electronic failure, a sudden power failure, physical shock, contamination of the drive's internal enclosure, wear and tear,or poorly manufactured platters and heads.
The HDD's spindle system relies on inside the to support the heads at their proper while the disk rotates.
HDDs require a certain range of air densities to operate properly.
The connection to the external environment and density occurs through a small hole in the enclosure about 0.
If the air density is too low, then there is not enough lift for the flying head, so the head gets too close to the disk, and there is a risk of head crashes and data loss.
Specially manufactured sealed and pressurized disks are needed for reliable high-altitude operation, above about 3,000 m 9,800 ft.
Modern disks include temperature sensors and adjust their operation to the operating environment.
Breather holes can be seen on all disk drives — they usually have a sticker next to them, warning the user not to cover the holes.
The air inside the operating drive is constantly moving too, being swept in motion by friction with the spinning platters.
This air passes through an internal recirculation or "recirc" filter to remove any leftover contaminants from manufacture, any particles or chemicals that may have somehow entered the enclosure, and any particles or outgassing generated internally in normal operation.
Very high humidity present for extended periods of time can corrode the heads and platters.
For GMR heads in particular, a minor head crash from contamination that does not remove the magnetic surface of the disk still results in the head temporarily overheating, due to friction with the disk surface, and can render the data unreadable for a short period until the head temperature stabilizes so called "thermal asperity", a problem which can partially be dealt with by proper electronic filtering of the read signal.
When the logic board of a hard disk fails, the drive can often be restored to functioning order and the data recovered by replacing the circuit board with one of an identical hard disk.
In the case of read-write head faults, they can be replaced using specialized tools in a dust-free environment.
If the disk platters are undamaged, they can be transferred into an identical enclosure and the data can be copied or cloned onto a new drive.
In the event of disk-platter failures, please click for source and imaging of the disk platters may be required.
For logical damage to file systems, a variety of tools, including on systems and onhard drive slot definition and function be used for.
Recovery from logical damage can require.
A common expectation is that hard disk drives designed and marketed for server use will fail less frequently than consumer-grade drives usually used in desktop computers.
However, two independent studies by and found that the "grade" of a drive does not relate to the drive's failure rate.
As of May 2019, the highest-capacity HDDs stored 14with plans to release 16 TB and 18 TB drives later in 2019.
As of 2016, the typical speed of a hard drive in an average desktop computer is 7200 RPM, whereas low-cost desktop computers may use 5900 RPM or 5400 RPM drives.
For some time in the 2000s and early 2010s some desktop users also used 10k RPM drives such as but such drives have become much rarer as of 2016 and are not commonly used now, having been replaced by NAND flash-based SSDs.
Mobile laptop HDDs Two enterprise-grade SATA 2.
Mobile HDDs spin at 4,200 rpm, 5,200 rpm, 5,400 rpm, or 7,200 rpm, with 5,400 rpm being typical.
Because of smaller platter smobile HDDs generally have lower capacity than their desktop counterparts.
There are also 2.
Enterprise HDDs Typically used with multiple-user computers running.
Examples are: transaction processing databases, internet infrastructure email, webserver, e-commercescientific computing software, and nearline storage management software.
Maximum capacity is not the primary goal, and as a result the drives are often offered in capacities that are relatively low in relation to their cost.
The fastest enterprise HDDs spin at 10,000 or 15,000 rpm, and can achieve sequential media transfer speeds above 1.
Drives running at 10,000 or 15,000 rpm use smaller platters to mitigate increased power requirements as they have less and therefore generally have lower capacity than the highest capacity desktop drives.
Enterprise HDDs are commonly connected through And nudges slots free features with or FC.
Some support multiple ports, so they can be connected to a redundant.
Enterprise HDDs can have sector sizes larger than 512 bytes often 520, 524, 528 or 536 bytes.
The additional per-sector space can be used by hardware RAID controllers or applications for storing DIF or Data Integrity Extensions DIX data, resulting click here higher reliability and prevention of.
Consumer electronics HDDs They include drives embedded into and.
The former are configured to provide a guaranteed streaming capacity, even in the face of read and write errors, while the latter are built to resist larger amounts of shock.
They usually spin at a speed of 5400 RPM.
Production is mainly in the Pacific rim.
Production of HDDs grew 16% per year, from 335 exabytes in 2011 to 693 exabytes in 2016.
Shipments declined 7% per year during this time period, from 620 million units to 425 million.
In 2018, Seagate has 40% of unit shipments, Western Digital has 37% of unit shipments, while Toshiba has 23% of unit shipments.
The lifespan or write endurance of SSDs is measured by either Terabytes Written TBW or Drive Writes Per Day DWPD.
In the case of the latter, if a 1 TB drive is rated for 1 DWPD, and the drive has a 1-year warranty, the Terabytes Written will be equal to 365.
The maximum for flash memory used in SSDs is 2.
The areal density of flash memory is doubling every two years, similar to 40% per year and faster than the 10—20% per year for HDDs.
As of 2018, the maximum possible capacity was 16 terabytes for an HDD, and 100 terabytes for an SSD.
HDDs were used in 70% of the desktop and notebook computers produced in 2016, and SSDs were used in 30%.
The usage share of HDDs is declining and could drop below 50% in 2018—2019 according to one forecast, because SSDs are replacing smaller-capacity less than one-terabyte HDDs in desktop and notebook computers and MP3 players.
The market for silicon-based flash memory NAND chips, used in SSDs and other applications, is growing rapidly.
Worldwide revenue grew 12% per year during 2011—2016.
As of March 2015available capacities for external hard disk drives ranged from 500 GB to 10 TB.
External hard disk drives are usually available as pre-assembled integrated products, but may be also assembled by combining an external with USB or other interface with a separately purchased drive.
They are available in 2.
Features such as biometric security or multiple interfaces for example, are available at a higher cost.
There are pre-assembled external hard disk drives that, when taken out from their enclosures, cannot be used internally in a laptop or desktop computer due to embedded USB interface on theirand lack of SATA or interfaces.
The term "DASD" includes other devices beside disks.

The motherboard is one of the most important parts of the PC, but as a tech enthusiast, you probably already know that.
What you might not know, though, is the role played by each chip, port or slot present on a hard drive slot definition and function />The role of the motherboard is to allow all these components to communicate with each other.
Considering the fact that all the other components hard drive slot definition and function installed on the motherboard or connected to it, it is safe to say that the motherboard click the following article the central piece of a PC, the component that brings it all jack and the beanstalk slot game />Processor Socket The processor socket is the central piece of a motherboard, usually being hard drive slot definition and function near the center of the motherboard.
Power Connectors No computer component can operate without power, and a motherboard is no exception.
The power connector, commonly a 20 or 24-pin connector, can be situated either near the right edge of the motherboard, or somewhere close to the processor socket on older motherboards.
Newer motherboards have an additional 4-pin or 8-pin connector near the processor, used to supply additional power directly to the processor.
The number of slots can vary, depending on motherboard, from 2, in low-end motherboards, all the way up to 8 memory slots, on high-end and gaming motherboards.
It is important to pay close attention to the type of memory a motherboard supports, in order to buy the appropriate memory modules.
Newer motherboards support DDR3 memory, the current industry standard memory architecture, but motherboards with DDR2 memory slots and even DDR1 memory slots are still present on the market.
An interesting aspect is that hard drive slot definition and function are some older motherboard models that supported different types of memory, and usually come with two DDR1 memory slots and 2 DDR2 memory slots, or two DDR2 slots and two DDR3 slots.
These motherboards were great options for people that wanted to upgrade a hard drive slot definition and function without having to upgrade all the other components as well.
The number of memory slots should be an important criterion to take into account when choosing a motherboard, as it will determine the maximum amount of memory you can install.
You may plan to or — do you really want to be limited by your motherboard in the process?
Coming in the form of a PCI-Express slot on newer motherboards or AGP on older ones, the video card slot is situated right below the processor.
At the opposite pole, high-end gaming motherboards come with multiple video card slots, allowing the installation of multiple video cards in a SLI or CrossFire configuration.
Expansion Slots Expansions have the role of letting you install additional components to enhance or expand the functionality of your PC.
You can install a TV tuner, a video capture card, a better soundcard, etc.
These ports are located under the video card slot, and come in the form of PCI slots on older motherboards or a scaled-down hard drive slot definition and function of PCI-Express slots on newer motherboards.
Some motherboards come with both types hard drive slot definition and function expansion slots.
The number of slots is usually dependent on the format of the motherboard — larger motherboards full ATX have more, while smaller formats micro-ATX have fewer, if any.
IDE and SATA Ports IDE and SATA ports are used to provide connectivity for the storage devices and optical drives.
It is not uncommon for manufacturers to include SATA ports of different revisions, such as two SATA2 ports and two SATA3 ports.
Considering the fact that most optical drives on the market come with a SATA connector, and these devices are not bandwidth-hungry, using a SATA2 port for an optical drive is perfectly acceptable.
BIOS Chip and Battery The BIOS chip contains the basic code needed to take your computer through the boot process, up to the point where the operating system takes over.
Since the BIOS code is stored on a memory chip that needs constant power to function, a battery is also present to keep the chip powered when the computer is unplugged.
This metal component is actually a heatsink, and its role is to provide thermal protection for the Northbridge — one of the most important components of a motherboard.
The northbridge is responsible for coordinating the data flow between the memory, the video card and the processor.
A secondary chip, known as Southbridge, has a similar function, coordinating the data flow between the processor and peripherals such as sound cards or network cards.
Front Panel Connectors, USB Headers and Audio Header The front panel connector is where all the elements present on the front of your case are connected.
Power button, reset button, power led, audio connectors and USB connectors — they are all connected to the front panel or the corresponding headers.
Rear Connectors These connectors are the bridge between the outside of your computer and the inside.
The name is a bit misleading, as the connectors are actually located on the left edge of the motherboard; however, since these connectors are accessible from the outside, the name simply implies where they are accessible from — the rear of the PC case.
External peripherals such as keyboard, mouse, monitor, speakers and so on are all connected via these connectors.
So there you have it, the parts of the motherboard and their functions, explained.
Now that you know how to choose your motherboard and build your dream PC, you might want to The article provides a detailed outline of two of the most popular operating systems, Linux and Windows, allowing you to determine which will suite your needs better.
