JMB394
Overview
JMicron JMB394 is a single chip, 1 to 5-ports 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. JMB394 uses JMicron’s production-proven Multi-port Serial ATA PHY technology and JMicron-proprietary storage processor to provide very high efficient SATA RAID operation. With an easy configuration scheme, the device can be a pure port multiplier 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. JMB394 also has advance mode to provide both benefit of performance boost and data protection. JMB394 is a self-contained storage processor chip which pletely frees up the main CPU loading and the SATA ports ply with e SATA specification, making it suitable for...
