SCSI is the abbreviation of Small Computer System Interface. It was first proposed in 1979. It is an interface technology developed for minicomputers. Now it has been widely used in minicomputers, high and low end servers and ordinary PCs.
SCSI can be divided into SCSI-1, SCSI-2, SCSI-3, and the latest is SCSI-3, which is also the most widely used SCSI version.
1. SCSI-1: Proposed in 1979, supports synchronous and asynchronous SCSI peripherals; supports 7 8-bit peripherals with a maximum data transfer speed of 5MB/s.
2. SCSI-2: Proposed in 1992, also known as Fast SCSI, the data transfer rate is increased to 20MB/s.
3. SCSI-3: Proposed in 1995, Ultra SCSI (Fast-20). Ultra 2 SCSI (Fast-40) appeared in 1997 with a maximum transfer rate of 80MB/s. In September 1998, Ultra 3 SCSI (Utra 160 SCSI) was officially released with a maximum data transfer rate of 160 MB/s. The Ultra 320 SCSI has a maximum data transfer rate of 320MB/s.
