Here is my Sata 3 results. I don't run on my sata 3 ports as this Marvell controller is bullshit. Kept getting hang ups and OS freezes. $300 waste of money on this Asus mobo. If I known then what I know now I would have just picked up a couple of these hdd's and a sata 2 mobo and ran with it and save some major money in the end. Now I have a $679 ssd that I can't reap the benefits of sata 3 with until I get another mobo. :(
