WD Intros 2TB Green Hard Drive

Western Digital Corp. (NYSE: WDC) on Tuesday introduced a 2-TB hard drive to its environmentally friendly Caviar Green product line.

WD believes many consumers are ready for such a large capacity drive to store video, pictures, audio, and other files in their expanding media libraries. Quoting market intelligence firm Trend Focus, the hard-drive maker claims about 10% of 3.5-inch drives sold today are at the 1-TB level or higher.

The Caviar Green product line is one of WD's most successful product lines. The line leverages WD's GreenPower, a collection of technologies designed to reduce power consumption. The drives are designed for use in USB, FireWire, and eSATA external hard drives, desktop computers, workstations, and desktop RAID environments.

The latest drive has a 32-MB cache and a SATA interface with a maximum data-transfer rate of 3 Gbps. The product consumes 7.4 watts in read/write mode and 4 watts at idle. In standby and sleep mode, the drive consumes less than a watt.The 2-TB drive, available at WD resellers and distributors, has a manufacturer suggested retail price of $299. The model number is WD20EADS.
