[ The PC Guide | Systems and Components Reference Guide | Hard Disk Drives | Hard Disk Interfaces and Configuration | Small Computer Systems Interface (SCSI) | SCSI Data Transfer Modes and Feature Sets ] Fast Wide SCSI Description: Fast Wide SCSI combines the features of Wide SCSI and Fast SCSI, so it uses 10 MHz SCSI bus speed on a 16-bit wide bus. This doubles the maximum transfer rate to 20 MB/s, the fastest bus defined under the SCSI-2 standard. This protocol is sometimes called Fast Wide SCSI-2. Defining Standard: SCSI-2. Special Features: None. Bus Width: Wide (16-bit). Signaling Method: SE or HVD. Signaling Speed and Bus Throughput: 10 MHz bus speed; 20 MB/s. Number of Devices Supported: 16. Termination: For SE, either active or forced perfect termination. For HVD, HVD termination. Cabling and Maximum Cable Length: "P" cable (68 pins). (Formerly, "A" cable plus "B" cable.)Maximum of 6m for SE, 25m for HVD.
