We've seen 3TB hard drives trickling onto the market for the better part of a year, but it's only now that we're seeing more UEFI-equipped motherboards that can actually handle all that storage capacity. So, the benchmarking wizards over at HotHardware decided now would be a fine time to pit a few of 'em against each other, rounding up models from the likes of Western Digital, Seagate and Hitachi and subjecting them to a grueling battery of 28 tests. We'll leave it to you to peruse the scores, but suffice to say the Seagate Barracuda XT swept about half the benchmarks, and notched a close second the rest of the time. But is it worth spending an extra $30 over Western Digital's consistently trailing Caviar Green? We'll leave that to you and your wallet.
