Specifacation

• With an easy configuration scheme, the device can be a pure port multiplier in a RAID configuration which provides SATA port expansion just like a SATA Hub, or hard-drive performance booster which provides a high performance device seen by host controller or hard-drive data protector which automatically backup data to prevent data loss from hard-drive damage. JMB393 also has advance mode to provide both benefit of performance boost and data protection.

• JMB393 is a self-contained storage processor chip which completely frees up the main CPU loading.
