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:
ATA-2 also was the first to note that devices other than hard drives could be attached to the interface: 3.1.7 Device: Device is a storage peripheral. Traditionally, a device on the ATA interface has been a hard disk drive, but any form of storage device may be placed on the ATA interface provided it adheres to this standard.
SATA is a computer bus interface for connecting host bus adapters to mass storage devices such as hard disk drives and optical drives. eSATA is a SATA connector accessible from outside the computer, to provide a signal (but not power) connection for external storage devices. [3]
A 3.5-inch Serial ATA hard disk drive A 2.5-inch Serial ATA solid-state drive. SATA was announced in 2000 [4] [5] in order to provide several advantages over the earlier PATA interface such as reduced cable size and cost (seven conductors instead of 40 or 80), native hot swapping, faster data transfer through higher signaling rates, and more efficient transfer through an (optional) I/O queuing ...
The ST-506 and ST-412 (sometimes written ST506 and ST412 [1]) were early hard disk drive products introduced by Seagate in 1980 and 1981 respectively, [1] that later became construed as hard disk drive interfaces: the ST-506 disk interface and the ST-412 disk interface. Introduced in 1980, the ST-506 was the first 5.25 inch HDD.
Small Computer System Interface (SCSI, / ˈ s k ʌ z i / SKUZ-ee) [2] is a set of standards for physically connecting and transferring data between computers and peripheral devices, best known for its use with storage devices such as hard disk drives.
