• 1-to-5 SATA III (6.0Gbps) Port Multiplier
  • Supports command-based and FIS-based switching
  • Supports ATAPI drives
  • Provides status (Link & Activity) LEDs for Host and Device ports
  • SCSI I 50pin Low Density Centronics Connector Form Factor

SPM575 is a One-to-Five SATA III Port Multiplier. It is designed to provide SATA port expansion, data protection and performance aggregation in various applications.

With an easy configuration scheme, the device can function as a pure port multiplier which provides SATA port expansion just like a SATA Hub, a hard drive performance booster which provides a high-performance device seen by the host controller, or a hard drive data protector which automatically backs up data to prevent data loss from hard drive damage.

SPM575 also has an advanced mode to provide both the benefits of performance boost and data protection.
