FastWide SCSI

nounStandard termTelecom & IT

An older parallel storage interface that combined a 16-bit bus with 10 MHz clock speeds.

FastWide SCSI is a legacy standard that doubled both the bus width and the clock speed of original SCSI implementations. By using a 16-bit wide cable and transferring at 10 megatransfers per second, it achieved a maximum theoretical throughput of 20 megabytes per second. It required a high-density 68-pin connector and precise active termination to maintain signal integrity over the parallel ribbon cables.
