SCSI bus interface, standards, manufacturers and distributors, technical information, books and test equipment, from the SCSI Technical Library of Information.
The narrow single ended SCSI bus supports a data transfer rate of 20 MB/sec. The single end SCSI bus may be up to 3 meters long with this transfer rate

SCSI: Why is SCSI better than IDE or EIDE?

SCSI can connect devices both inside and outside the box with up to 7 drives on a narrow bus or up to 15 drives on a wide bus versus IDE is limited to an 18 inch bus, inside the box with 2 devices per bus. IDE buses execute one command at a time versus SCSI allows queuing to each of the devices on the bus. IDE takes up to 95% of the CPU during data transfers, SCSI only uses about 5% of the CPU for buffer management. For more questions and answers, go to STA's Website.
