Small Computer Systems Interface (SCSI)

SCSI (pronounced “scuzzy”) is the acronym for Small Computer System Interface, a high performance parallel peripheral interface that can independently distribute data among peripherals attached to the PC. Unlike ATA, SCSI incorporates those instructions needed for communication with the host PC. Freeing the host computer from this job makes it more efficient in performing its user-oriented activities. SCSI is a specification for a peripheral bus and command set defined in an ANSI standard X3.131-1986.

SCSI drives are usually more suitable for high-end computer systems, which require maximum possible performance. SCSI provides for higher data transfer rates and less CPU load than ATA but also has higher ...
