SCSI celebrates its 20th anniversary with a bang by moving to the seventh generation of the bus that introduces a maximum data transfer at a staggering 320 MB/sec. Over the course of the past
two decades the protocol has evolved from an 8-bit, single-ended interface transferring data at 5 MB/sec to a 16-bit, differential interface transferring data at 160 MB/sec. For the first time the SCSI protocol has been revised in order to reduce the time spent on processing overhead, resulting in increased performance.
