JMicron/JMB322
JMB322 RAID Port Multiplier
Overview
The JMicron JMB322 is a single chip, 1 to 2-port Serial ATA II Port Multiplier with RAID function support. It is designed to provide SATA port expansion, data protection and performance aggregation at various applications. The device uses JMicron’s production-proven Multi-port Serial ATA PHY technology and JMicron-proprietary storage processor to provide very high efficient RAID operation. With an easy configuration scheme, the device can be a pure port multiplier which provides SATA port expansion just like USB 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.
