Why is SCSI better?
SCSI drives come in 10,000 or 15,000 rotations per minute (RPM) versions, meaning it will access data much faster than your desktop will (desktop drives are generally 5400 or 7200 RPM). If you have mission-critical applications that aren't too big but need to be accessed quickly, SCSI is a great choice.
