Small Computer System Interface (SCSI) is the second most popular drive interface in use today after
the Integrated Drive Electronics (IDE)
interface. SCSI is faster than IDE and supports more devices. SCSI devices, such as hard disk drive and
CD-ROM drive, are better suited in a
network environment in which many users access shared drives simultaneously. SCSI has three
standards: SCSI-1, SCSI-2, and SCSI-3.
