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.
