Addonics ADSA3GPX8-4E - storage controller (RAID) - eSATA 3Gb/s - PCIe x8

Designed to the latest 3Gbits/sec ASIC from Silicon Image and eSATA connector, this 4-port controller incorporates many advanced features that are only found in some expensive RAID controllers. With the onboard RAID firmware, the 4 eSATA ports can be easily configured as 4 individual ports with no RAID or with RAID 5, RAID 0, RAID 1, RAID 10, RAID 1+S, or JBOD (a feature of combining all 4 drives into one large capacity hard drive)

When installed into the fast PCI-Express BUS, this controller ensures maximum data throughput of 3 Gbits/sec per port. In addition, the latest External SATA (eSATA) connector also provides more secured cable connection, improved durability, increased EMI protection and up to 2 meters cable length.
