Introduction

SPM394 is 1 to 5 SATA Port Multiplier RAID Controller with LCD Module. It is designed to provide SATA port expansion, data protection and performance aggregation at various applications.
SPM394 uses market-proven Multi-port Serial ATA PHY technology and 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. SPM394 also has advance mode to provide both benefit of performance boost and data protection.
SPM394 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
