A standard method of interfacing a computer to disk drives, tape drives and other peripheral devices that require high-speed data transfer. Up to seven SCSI devices can be linked to a single SCSI port. Contrast with ST-506, EDSI, IDE.
(SCSI) - Pronounced "skuzzy," this is a standard data pathway used mostly for hard drives and CD-ROM drives; but it was also a common interface for scanners and even printers at one point. It is the fastest (and the most flexible) method of interfacing with hard drives. It comes in numerous varieties, and is mainly used in servers and high-end workstations. SCSI drives are much more expensive than IDE drives, but SCSI drives can have features, like 15,000 RPM spin speeds and 5-year warranties, that IDE drives currently do not.
