  Adaptec 1520 ISA SCSI Kit
  

  Ideal for connecting hard drives and other high-performance SCSI peripherals to your PC

  Product Highlights

   

  • 10 MB/sec synchronous burst rate on the SCSI bus
  • Plug-and-Play installation
  • Adaptec EZ-SCSI® software

  Overview

  Today's rapid growth in file sizes -- thanks to multimedia, new software applications, and the Internet -- requires larger hard drives, file servers, and high-performance peripherals for storing this information. The AHA-1520B host adapter provides the ideal solution for connecting these devices to a PC.

  Key Benefits

  Connection to Any SCSI Peripheral

  The AHA-1520B is a complete kit with everything needed to connect up to 7 SCSI devices to a PC. These devices include internal and external hard drives, CD-ROM and CD-Recordables, tape and removable drives, scanners, and more.

  Unmatched Compatibility and Reliability

  As with all Adaptec host adapters, the AHA-1520B has undergone rigorous compatibility testing in Adaptec test labs. With extensive compatibility, functionality, and environmental testing, users are assured of having a product that works seamlessly with virtually any SCSI device available.

  Maximize Peripheral Performance

  The AHA-1520B 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-1520B 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.

  Easy to Install and Use

  Features such as Plug-and-Play ensure installing the AHA-1520B is quick and easy. Add Adaptec EZ-SCSI software (included) for MS-DOS® and Windows®, and the adapter takes care of everything -- including determining which SCSI devices are present, setting termination automatically, loading necessary drivers, and modifying the system configuration files. And, our powerful Adaptec SCSISelect® optimization utility makes tuning the host adapter configuration a snap.

  Quality You Can Depend On

  The AHA-1520B host adapter has received thousands of hours of reliability testing. Known for quality, Adaptec continues to deliver standard-setting products that are incorporated into the systems of virtually all major computer and peripheral manufacturers around the world.
