The AHA-1522B allows users to take advantage of SCSI's fast connection for their peripherals. With increased data transfer rates and drastically reduced wait times over parallel interface peripherals, AHA-1522B users will experience a dramatic increase in system performance. And since SCSI is the only connection that allows attachments to multiple external as well as internal peripherals, users get more connectivity for their systems with just one card.
