When computer technology takes a step forward, it is sometimes better to stick with the status quo and let someone else help the industry recoup their R&D investment. When video cards first jumped from the AGP slot to PCI Express, for instance: PCI Express videocards didn't deliver enough of a performance boost to justify buying a whole new motherboard. We could be seeing the same scenario unfold with the next generation of hard drive interface, known as SATA 6Gb/s - but since Seagate's 2TB Barracuda XT currently is the only hard drive you can buy today that uses the new standard, it's impossible to know. Theoretically, the SATA 6Gbps delivers twice the throughput of the previous standard, SATA 3Gb/s (as you've no doubt guessed, six gigabits per second compared to three gigabits per second); in the real world, it didn't matter much which interface we connected the Barracuda XT to.
