As the title really, I'm just about to research setting up a raid array ( ? ) and I have 3 ssd's 1 samy 840 pro 250gb, an Intel 530 160gb and an OCZ 60gb. Are they compatible, or doesn't it matter ? Either way I'm going to add another 250gb at some point,( maybe more if they need to be the same ) and drop the 60gb, into my spare rig.
