In computing, Serial Attached SCSI (SAS) is a point-to-point serial protocol that moves data to and from computer-storage devices such as hard disk drives, solid-state drives and tape drives. SAS replaces the older Parallel SCSI (Parallel Small Computer System Interface, usually pronounced "scuzzy" [ 3 ] [ 4 ] ) bus technology that first ...
The earliest hard disk drive (HDD) interfaces were bit serial data interfaces that connected an HDD to a controller with two cables, one for control and one for data. [a] An additional cable was used for power, initially frequently AC but later usually connected directly to a DC power supply unit. The controller provided significant functions ...
Barracuda hard disk from an Alphaserver (4.3 GB) The Seagate Barracuda is a series of hard disk drives and later solid state drives produced by Seagate Technology that was first introduced in 1993. [3] The line initially focused on high-capacity, high-performance SCSI hard drives until introducing ATA models in 1999 and SATA models in 2002.

The Western Digital Raptor (often marketed as WD Raptor, 2.5" models known as VelociRaptor) is a discontinued series of high performance hard disk drives produced by Western Digital first marketed in 2003.
While hardware RAID controllers have been available for a long time, they initially required expensive Parallel SCSI hard drives and aimed at the server and high-end computing market. SCSI technology advantages include allowing up to 15 devices on one bus, independent data transfers, hot-swapping , much higher MTBF .
