Introduction

SPM394 is a One-to-Five SATA Port Multiplier RAID Controller with LCD Module. It is designed to provide SATA port expansion, data protection and performance aggregation in various applications.

SPM394 uses market-proven Multi-port Serial ATA PHY technology and a proprietary storage processor to provide very highly efficient SATA RAID operations.

With an easy configuration scheme, the device can function as a pure port multiplier which provides SATA port expansion just like a SATA Hub, a hard drive performance booster which provides a high-performance device seen by host controller, or a hard drive data protector which automatically backs up data to prevent data loss from hard drive damage.

SPM394 also has an advanced mode to provide both the benefits of performance boost and data protection.

SPM394 is a self-contained storage processor chip which completely frees up the main CPU loading and whose SATA ports comply with the eSATA specification, making it suitable for use in both internal system and external storage applications.
