Western Digital has announced that the company is shipping the world's largest capacity SATA hard drive. As the latest addition to its WD Caviar Green family, the new hard drives deliver up to a massive 3 terabytes (TB) of storage capacity on a single drive.

WD Caviar Green drives are an eco-friendly storage solution with WD GreenPower Technology, which reduces power consumption by enabling lower operating temperatures for increased reliability and decreases acoustical noise for quiet operation. The WD Caviar Green 2.5 TB and 3 TB hard drives are designed for use as secondary external storage and next-generation PC storage in 64 bit-based systems.

WD is bundling its WD Caviar Green 2.5 and 3 TB hard drives with an Advanced Host Controller Interface (AHCI)-compliant Host Bus Adapter (HBA), which will enable the operating system to use a known driver with correct support for large capacity drives.

"With our WD Caviar Green drives, we enable energy-conscious customers to build systems with the highest capacities that deliver the optimal balance of system performance, ensured reliability and energy conservation," said Sushil Bandi, Country Manager for the Indian Subcontinent, Western Digital. "Customers will be able to take advantage of this breakthrough capacity point now for secondary external storage in legacy 32-bit systems that run on Microsoft Vista or Windows 7 platforms."

Manufacturer's Suggested Retail Price (MSRP) for the WD Caviar Green 2.5 TB hard drive is Rs.9,000/- and the 3 TB hard drive is Rs.11,500/-. WD Caviar Green hard drives are covered by a three-year limited warranty. WD Caviar Green 2.5 TB hard drives (model number WD25EZRSDTL) and 3 TB hard drives (model number WD30EZRSDTL) will be available in India later this year.
