JMicron/JMB392
JMB392 RAID Port Multiplier Chip
1. Overview
JMicron JMB392 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.
JMB392 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. JMB392 also has advance mode to provide both benefit of performance boost and data protection.
JMB392 is a self-contained storage processor chip which completely frees up the main CPU loading and
the SATA ports comply with eSATA specification, making it suitable for use in both internal system and
external storage applications
