Are you planning to connect external storage to your computer? There's a good chance the storage enclosure will have two or more interfaces from which to choose, including FireWire®, USB, and eSATA. Your computer has USB ports, and may have FireWire ports, too. So if you can just plug into your computer's existing ports, why use an eSATA card? Consider the fact that the eSATA interface offers significantly superior performance to that of FireWire 800 and USB 2.0 interfaces. Sonnet's Tempo™ edge™ SATA 6Gb/s ExpressCard/34 is an affordable solution for adding fast eSATA connectivity through an adapter that practically disappears inside your computer.
