Differential
New SCSI designs will use drives with the Ultra2 SCSI Ultra2 low-voltage differential (LVD) doubles Wide SCSI bus data rates to 80 Mbytes/sec, increases bus cable lengths to 12 meters, and provides the capability to add up to 15 peripherals on the bus Ultra2 SCSI is backward-compatible to previous versions of SCSI
