Six months after showing off the demo, Seagate announced Monday that it is now shipping what it says is the word's first 3.5-inch 6Gbps 2TB hard drive. The drive is based on the third generation of the Serial ATA (SATA) standard, roughly called SATA3. The majority of existing hard drives use the SATA2 standard that caps at 3Gbps. Theoretically, the new 6Gbps standard's throughput could be fast enough to transfer the entire contents of a CD (about 800MB) in just one second. The new hard drive is called Barracuda XT, and it belongs to the company's mainstream line of desktop hard drives. It spins at 7200rpm and boasts 64MB of cache memory, as opposed to the 16MB or 32MB of most existing hard drives. It is a four-platter drive with an areal density of 368 gigabits per square inch. Of course, to take advance of the new 6Gbps throughput speed, the Barracuda XT needs to be installed in a computer with a 6Gbps SATA controller. The good news is that's also available now.
