Small Computer Systems Interface (SCSI)


Small Computer Systems Interface (SCSI)

SCSI is a computer data communication standard devised by the Apple Computer Corporation and standardized by the American National Standards Institute (ANSI) to allow personal computers to communicate with components such as hard disks, printers, cd-rom players and writers, tape drives, scanners and so forth.

The main advantage of SCSI over EIDE is speed and transfer rate. The latest SCSI-2 Ultra standard has a top data transfer speed of 80 Mb per second. Somewhat faster than the Ultra DMA/66.

 

Another plus of the SCSI standard is in that it allows devices to be daisy chained. One device can be hooked up to another instead of each in a separate port, as is the case with PCI. This new Universal Serial Bus (USB) has this multi-linking in common with SCSI.
