What is SE transfer?
single-ended transfer -- uses one wire to transfer each data signal
What is HVD transfer?
high-voltage differential -- sends each data signal over a pair of wires in a manner that resists interference

supports greater cable lengths than SE
What is the max. cable length of SCSI-1 systems?
6 meters
What is the max. cable length of SCSI-2 systems?
6 meters
What is the max. cable length of Fast SCSI-2 systems?
3 meters for SE
25 meters for HVD
What is the max. cable length of Wide SCSI-2 systems?
3 meters for SE
25 meters for HVD
What is the max. cable length of Fast Wide SCSI-2 systems?
3 meters for SE
25 meters for HVD
What is the max. cable length of Ultra SCSI systems?
3 meters if 4 or fewer devices
1.5 meters if more than 4 devices
What is LVD transfer?
low-voltage differential -- components require less power to operate & can operate faster; allows longer cable lengths
