It detected the card, but made all the onboard SATA devices disappear, and Asus support couldn't make it play nice with the onboard controller. Amazingly, the vendor took it back after stipulating "no returns", and promised to reimburse the $14.50 shipping back to China. Now I'm stuck without an SAS card. Any other HBA card recommendations? Are the 9211 cards older than the 9220, I'm assuming? I don't really want to spend more than $125. Thanks, Alex
