| Short for Small Computer System Interface, SCSI, pronounced as "Scuzzy", is the second most commonly used interface for disk drives. Unlike competing standards, SCSI is capable of supporting eight devices, or sixteen devices with Wide SCSI. SCSI-1 is the original SCSI standard developed back in 1986 as ANSI X3.131-1986. SCSI-1 is capable of transferring up to eight bits a second. SCSI-2, approved in 1990, added new features such as Fast and Wide SCSI, and support for additional devices. SCSI-3 was approved in 1996 as ANSI X3.270-1996. SCSI is a standard for parallel interfaces that transfers information at a rate of eight bits per second and faster, which is faster than the average parallel interface. SCSI-2 and above
supports up to seven peripheral devices, such as a hard drive, CD-ROM, and scanner, that can attach to a single SCSI port on a system's bus. SCSI ports were designed for Apple Macintosh and Unix computers, but also can be used with PCs.
