Four RAID-ready external SATA II ports for your high performance SATA II 3Gb/sec hard drives!  Provides improved performance over comparable SATA RAID controllers by offering a PCI-X/133 MHz host interface with bandwidth up to 1056 MB/s, which is twice as much as a common 64bit PCI interface.  Plus, its four 3Gb/s external (eSATA) ports can deliver drive throughputs of up to 300 MB/s (3Gb/s) each!

This card supports "direct connect" drive enclosures like the 4-Bay Hot-Swap SATA RAID Case Kit and the Fusion 400 eSATA 4 Bay SATA II Hot Swap Drive Enclosure allowing you to use 4 individual drives or configure as RAID 0, RAID 1, RAID 1+0, RAID 1+S, RAID 5!  Plus, it also compatible with Port Multiplier enclosures like the 5-Bay SATA Port Multiplier Enclosure with LCDs and the Sonnet Fusion 500P, eSATA Port Multiplier Enclosure allowing you to connect up to five drives in one enclosure through a single cable. Using 2TB drives, you can connect an astounding 40 Terabytes (40,000 Gigabytes!) of storage!
