SCSI Protocol Map
The table below shows how the two most important protocol characteristics--bus width and bus speed--map into the different names for SCSI transfer modes and feature sets that are commonly seen in the SCSI world. Links are included to each of the SCSI transfer modes or feature sets. The throughput for each SCSI variety is also shown:
