Product Overview

Silicon Image’s SATARaidTM provides Serial ATA Software RAID including Striping and Mirroring to enhance the industry’s first proven PCI-to-SATA host controller product. Two major challenges facing the storage industry today are keeping pace with the increasing performance

demands of computer systems by improving disk I/O throughput and providing data accessibility in the face of hard disk failures. With the SiI 3112 / Sil 3512 Serial ATA host controller and SATARaid, both of these problems are solved.

RAID Striping greatly improves hard disk I/O performance by concurrently Striping data across mul- tiple drives. RAID Mirroring enables users to enjoy the confidence of data availability regardless of a single disk failure as data is simultaneously written to two drives.

Standard with SATARaid software is a Graphical User Interface (GUI) that provides easy-to-use configu- rations for the different RAID Sets supported.
