SSDs are already pushing Sata 3gb to the limit, and sata6 will have improvements in more things than just data output (queueing, etc).What's the deal with that anyway, I doubt we'd have a mechanical drive that will be faster than that electronic port anyway. The read/write speeds achieved by your harddrive won't be 3GB/s anytime soon, let alone 6GB. Unless I can see some real performance differences, I call it marketing based on theorethical numbers, not practical performance.
