Make the jump to Serial ATA performance with a four-port RAID card from StarTech.com. You get four RAID-ready internal Serial ATA ports for your high performance Serial ATA hard drives. Whether you need Striping (RAID 0), Mirroring (RAID 1), or both (RAID 0+1), this card has your need covered. The card also supports RAID 1+S (Mirrored-Sparing), which automatically replaces a failed hard drive and rebuilds the system if a booting hard drive fails. The PCISATA4R1 comes with an interchangeable bracket, letting it fit in both Low Profile and standard configurations.
