What my main question is the asus p8z68 v pro gen 3 only has 2 sata III 6gb/s connections and i have bought one ssd that will use one of those connections and then i bought two wd caviar black 6gb/s 64mb cache sata III drives. I will only have one more connection for the sata III after using one for the ssd. Can i connect one wd hdd to the other sata III and one to a sata II and not lose transfer speed? or is there another way to do this to get optimal performance out of that wd hard drive. sorry about posting the same question twice but this is a better explanation of my problem. Thanks again.
