Pronounced “scuzzy”. Variations of the SCSI interface provide for faster data transmission rates than standard serial and parallel ports (up to160 megabytes per second). The variations includeFast/Wide SCSI: Uses a 16-bit bus, and supports data rates of up to 20 MBps.SCSI-1: Uses an 8-bit bus, and supports data rates of 4 MBps.SCSI-2: Same as SCSI-1, but uses a 50-pin connector instead of a 25-pin connector, and supports multiple devices.IBM TS22xx - TS2290, TS2280, and TS2270 149
