Seagate Beefs Up Desktop Hard Drive to 1.5TB

Seagate announced today it is debuting three new internal hard drives, including what it calls the "world's first 1.5-Terabyte" desktop focused drive. The other two drives are half-terabyte models (500GB) which designed for notebooks.

Seagate's announcement of the 1.5TB Barracuda 7200.11 ups the ante between it, Hitachi and Samsung for the world's largest hard drive. Hitachi, in fact, is just getting around to shipping its second generation 1TB drive, which it claims is also energy efficient.

The new Seagate Barracuda 7200.11, according to Seagate, uses just four platters for its 1.5TB of storage and makes use of perpendicular magnetic recording technology for capacity boosting. This 3.5-inch internal hard drive also sports a Serial ATA 3GB/sec interface for a reported sustained data rate of up to 120MB/second.

The two notebook hard drives, meanwhile, are the 2.5-inch Momentus 5400.6 and Momentus 7200.4. Both make use of a Serial ATA 3GB/sec interface like the desktop hard drive.
