IDE/ATA is more popular due to the fact that IDE/ATA devices tend to be cheaper.
Short for Small Computer Systems Interface. The original SCSI protocol. ANSI standard X3.131-1996. Busspeed 5 MHz. Datawidth 8 bits.
SCSI-II adds support for CD-ROM's, scanners and tapedrives.
Uses the busspeed of 10MHz instead of the original 5MHz.
Uses 16 bits instead of the original 8 bits.
Uses the busspeed of 20MHz.
