It's a StarTech pexesata1. Nobody claims that Win 7 /64 will work with their cards but in the customer comments pages many say they are detected. It is in the device manager under Silicon Image but not in the Bios. I have downloaded their
drivers, etc, and the Cavalry 1TB external drive is good because it works with USB and it is the second new one in 2 weeks. The first one had the "click of death".
