Seagate announced that it is first to ship a SATA III desktop hard-drive with the Seagate Barracuda XT 2TB SATA III HDD (ST32000641AS).
The Seagate Barracuda XT is a 7200RPM HDD featuring 2TB of storage capacity and the new blazing fast Serial ATA (SATA) 6Gb/second interface. Of course to leverage the new speeds you need a new motherboard with a SATA III interface like the recently announced Asus P7P55D Premium. The Barracuda XT HDD, a four-platter drive featuring an areal density of 368 Gigabits per square inch, delivers the highest performance – burst speeds of up to 6 Gigabits per second – for all PC applications, maintains backward compatibility with the SATA 3Gb/second and SATA 1.5Gb/second interfaces, and uses the same cables and connectors as previous SATA generations to ease integration. The hard drive’s SATA 6Gb/s interface enables system builders using SATA 6Gb/s drive controllers to build high-performance desktop PCs, full-tilt gaming rigs, and home and small business servers, and its 64MB cache optimizes burst performance and data transfer speeds.

The Seagate 2TB SATA III ST32000641AS should arrive at shops soon for about $299. Check NewEgg.
