Hello. Erm, I need a pretty big hard drive, and it seems all the ones above a certain storage capacity are labelled SATA-II on OCUK. Now this was fine but there didn't seem to be half as many motherboards which were labelled as supporting SATA-II when I was just looking. However there are a few that are labelled as having SATA 3Gb/s. Are these the same thing? Should I assume most motherboards support SATA-II unless otherwise stated? It's confusing me a bit but I just wanted to make sure that what i got was compatible...Thanks.
