What is Ultra SCSI?
Ultra SCSI is also called "Fast-20". It is an enhancement of SCSI that results in doubling the FAST SCSI data throughput speeds to 20MBps for 8bit and 40MBps for 16bit. It reduces the maximum allowable single-ended SCSI cable length to 1.5m for five to eight addresses and 3m for four or fewer addresses. Maximum allowable differential (HVD) SCSI cable length is 25m. It is defined in the SPI document of the SCSI-3 spec.
