Wide SCSI

hardware, standard A variant on the SCSI-2 interface. It

uses a 16-bit bus - double the width of the original SCSI-1

- and therefore cannot be connected to a SCSI-1 bus. It

supports transfer rates up to 20 MB/s, like Fast SCSI.

There is also a SCSI-2 definition of Wide-SCSI with a 32 bit

data bus. This allows up to 40 megabytes per second but is

very rarely used because it requires a large number of wires

(118 wires on two connectors). Thus Wide SCSI usually means

16 bit-wide SCSI.
