The SATA 3.0 spec—which doubles transfer speeds from 3Gbps to 6Gbps—was officially released in May, and it looks like Seagate is first out the gate with actual hardware (no surprise), the 2TB Barracuda XT.
The four-platter drive has also got a massive 64MB cache, necessary, really, with that much space. You just need a brand new motherboard to use it—or add-on controllers, though it is backward-compatible with legacy SATA ports. Oh, and 300 bucks. [Seagate, Image via Scoblizer]
