Some desktop- and laptop-class disk drives allow the user to make a trade-off between seek performance and drive noise. For example, Seagate offers a set of features in some drives called Sound Barrier Technology that include some user or system controlled noise and vibration reduction capability. Shorter seek times typically require more ...
Also, while earlier versions of the technology only monitored hard drive activity for data that was retrieved by the operating system, this latest S.M.A.R.T. tests all data and all sectors of a drive by using "off-line data collection" to confirm the drive's health during periods of inactivity.
In computer data storage, a volume or logical drive is a single accessible storage area with a single file system, typically (though not necessarily) resident on a single partition of a hard disk. Although a volume might be different from a physical disk drive, it can still be accessed with an operating system's logical interface.
Density is a measure of the quantity of information bits that can be stored on a given physical space of a computer storage medium.There are three types of density: length (linear density) of track, area of the surface (areal density), or in a given volume (volumetric density).
IBM in its 1983 release of PC DOS version 2.0 was an early if not first use of the term partition to describe dividing a block storage device such as an HDD into physical segments. The term's usage is now ubiquitous. [citation needed] Other terms used include logical disk, [4] minidisk, [5] portions, [6] pseudo-disk, [6] section, [6] slice [7 ...
A solid-state drive (SSD) is a type of solid-state storage device that uses integrated circuits to store data persistently. It is sometimes called semiconductor storage device, solid-state device, or solid-state disk. [1] [2] SSDs rely on non-volatile memory, typically NAND flash, to store data in memory cells. The performance and endurance of ...
RAM drive – a block of random-access memory that the operating system treats as if it were secondary storage; Sequential access memory – a class of data storage devices that read stored data in a sequence; Wear leveling – a technique for prolonging the service life of some kinds of erasable computer storage media, such as flash memory
An example of primary storage. 15 GB PATA hard disk drive (HDD) from 1999. When connected to a computer it serves as secondary storage. 160 GB SDLT tape cartridge, an example of off-line storage. When used within a robotic tape library, it is classified as tertiary storage instead. Read/Write DVD drive with cradle for media extended
