|This 2S2I PCI Express SATA/IDE Combo Controller Adapter Card lets you add two Serial ATA (SATA) (one internal, one external) and two IDE channels (2 IDE drives per channel) to a computer, through a single PCIe slot. The SATA/IDE combo adapter card offers a hardware RAID solution with support for RAID 0, RAID 1 and JBOD, allowing you to configure your SATA drives to meet individual storage needs.|
I got this card to provide an eSATA connection to an external enclosure that had both USB 2.0 / eSATA interfaces. The device installed and worked without a hitch. I haven't performed any performance testing, though device response (500 GB backup drive) is quite snappy now. I've only thus far used the eSATA interface, though an internal SATA and two IDE/133 are also possible. Sweet! I'll probably pick up another one for one of my other systems.
