I was wondering which one I should choose, and why. Keep in mind that I definitely like the 1.5 TB model more, but will I need the 6.0Gb/s on the 1 TB model? I'll be using my PC for gaming. Here are my specs:
Because these drives are not bottlenecked at the transfer speed they are bottlenecked by the fact that they are spinning mechanical drives. The new SATA III (6.0 Gb/s) is only really utilized by solid state disks. A lot of people think there will be a big increase in speed using the new interface but the old interface is fine for all but the fastest disks which would only see a small speed increase. Solid state drives are capable of very fast transfer speeds and can actually max out the ability of SATA II.
