Western Digital launches 2TB hard drive

The 3.5-inch Caviar Green range now goes up to two terabytes, the largest capacity yet for one HDD

Western Digital has launched the first 2TB internal hard disk drive, as the latest addition to its WD Caviar Green series.

The 3.5-inch drive was announced on Tuesday. Caviar Green is Western Digital's range of "environmentally friendly" HDDs. The drives use a technology called IntelliPower to fine-tune spin speed, transfer rate and caching algorithms, to reduce power consumption. Western Digital claims this results in a saving of four to five watts over standard desktop drives.

The 2TB drive uses four 500GB platters, each platter with 400Gb-per-square-inch areal density. It has a transfer rate of 3Gbps and a 32MB cache, and can be installed inside a PC or in an external hard-drive casing. Western Digital claims the drive is cool and quiet enough to be put into a fanless external casing.

The recommended retail price of the drive is $299 (£211). Although specific UK pricing has not been announced, various retail websites are listing the drive for between £205 and £230.
