Disk drive interfaces have evolved from simple interfaces requiring complex controllers to attach to a computer into high level interfaces that present a consistent interface to a computer system regardless of the internal technology of the hard disk drive. The following table lists some common HDD interfaces in chronological order:
A hard disk drive (HDD), hard disk, hard drive, or fixed disk [a] is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating platters coated with magnetic material.
In the list those manufacturers that also produce hard disk drives or flash memory are identified. Additionally, the type of memory used in their solid-state drives is noted. Additionally, the type of memory used in their solid-state drives is noted.
A disk drive is a device implementing such a storage mechanism. Notable types are hard disk drives (HDD), containing one or more non-removable rigid platters ; the floppy disk drive (FDD) and its removable floppy disk ; and various optical disc drives (ODD) and associated optical disc media.
The notion of "large" amounts of data is of course highly dependent on the time frame and the market segment, as storage device capacity has increased by many orders of magnitude since the beginnings of computer technology in the late 1940s and continues to grow; however, in any time frame, common mass storage devices have tended to be much larger and at the same time much slower than common ...
The SMD interface is based upon a definition of two flat interface cables ("A" control and "B" data) which run from the disk drive to a hard disk drive interface and then to a computer. This interface allows data to be transferred at 9.6 Mbit/s. The SMD interface was supported by many 8 inch and 14 inch removable and non-removable disk drives.
This category revolves around various types of rotating disk computer storage media.The discs may be permanently attached to, or removable from, the computer. For large computer systems such as mainframes and server farms, the discs may be connected to a network, and thus may be situated physically distant from the computers they serve.
The physical phenomena on which the device relies (such as spinning platters in a hard drive) will also impose limits; for instance, no spinning platter shipping in 2009 saturates SATA revision 2.0 (3 Gbit/s), so moving from this 3 Gbit/s interface to USB 3.0 at 4.8 Gbit/s for one spinning drive will result in no increase in realized transfer rate.
