- SCSI-1 calls for a cable with 8 data wires plus one for parity.
- SCSI-2 allows use of multiple cables to support 16- or even 32-bit data transfers in parallel.
- SCSI-3 allows use of multiple cables to support 32- or even 64-bit data transfers in parallel.
- With fast SCSI it's possible to transfer 40MB of data per second on a single SCSI cable.
