Western Digital has today announced the WD Caviar Green 2TB hard drive - the industry's highest capacity drive to date.
With four 500GB platters boasting an areal density of 400 Gigabits per square inch, the WD20EADS also features the highest density platters we've seen to date, beating the Seagate 7200.12's areal density of 329 Gigabits per square inch by a significant margin.
The Green features a 32MB cache, a response time of 14.5ms and has claimed data transfer rates of 100MB/sec. Spindle speeds are not disclosed by Western Digital because the drive uses its IntelliPower power saving feature that regulates spindle speed, transfer rate and caching algorithms to deliver a balance of power efficiency and good performance.
The Green 2TB also includes Western Digital's StableTrac technology which, according to the company, secures the motor shaft at both ends to reduce system-induced vibration and stabilises platters for accurate tracking during read and write operations. It's a technology that has been featured on the company's Black series drives for a while.
"Saving power without sacrificing storage capacity is what consumers want, and what many businesses are requiring today. With the launch of the new WD Caviar Green 2 TB hard drive, customers receive the additional capacities needed to operate today's highly advanced programs and high-resolution digital files while using less power than typical drives with similar performance and capacities,
" said Jim Morris, WD senior vice president and general manager of client systems.
Overclockers UK currently has the drive up for pre-order at just over £205 (inc. VAT)
, which is quite a bit more than you'll pay for two Samsung SpinPoint F1 1TB drives, but this will use less power and everything is in one place.
We should have one of the Green 2TB drives in the labs very soon, so stay tuned for the full review. In the meantime, feel free to discuss the news in the forums
