Hard Drives help minimize energy consumption.

Press Release Summary:

Offered in capacities of 500 GB, 750 GB, and 1 TB, GreenPower(TM) WD RE2-GP Hard Drives feature IntelliPower(TM) technology, which balances spin speed, transfer rate, and caching algorithms for power savings. IntelliSeek(TM) calculates optimum seek speeds, while IntelliPark(TM) automatically unloads recording heads during idle to minimize aerodynamic drag and disables read-write channel electronics. Monitoring workload, drives automatically invoke idle mode whenever possible.

WD® Enterprise GreenPower(TM) Hard Drives Reduce Energy Consumption, Significantly Lowering Costs for Data Centers

WD RE2-GP Drives Deliver the Lowest Power Consumption and Solid Performance for Enterprise Customers

LAKE FOREST, Calif., Nov. 12 /-- Western Digital Corp. (NYSE:WDC) today announced its new environmentally friendly, energy-conscious GreenPower(TM) family of WD(R) enterprise hard drive products. The new WD RE2 GreenPower (GP) family offers capacities of 500 gigabytes (GB), 750 GB and one terabyte (TB), and provides data-hungry organizations with a money-saving solution to combat the challenges faced in the enterprise IT sector, such as, total available drive slots, maximum capacity, and available power and budget. Addressing a growing high-capacity enterprise market, WD RE2 drives are reliability-rated at 1.2 million hours MTBF (mean time between failure) in high duty cycle environments.

"Delivering up to 40 percent savings in hard drive power consumption, Western Digital's new RE2-GP hard drives are an excellent choice for customers deploying Rackable Systems' newest generation of Eco-Logical storage systems -- enabling even greater efficiency and performance," said Tony Gaughan, chief products officer of Rackable Systems.

WD RE2-GP hard drives are designed with power savings as the primary attribute. The WD RE2-GP hard drives offer massive capacity with significant power savings and lower total cost of ownership compared to other competitive enterprise-class drives.

"Verari Systems is dedicated to protecting the environment by providing data center solutions that are engineered for maximum power efficiency," said David Driggers, chief technology officer of Verari Systems. "By utilizing WD's latest GreenPower technology, Verari is able to provide enterprise customers with a solution that delivers one of the most energy-efficient systems available today."

According to the U.S. Environmental Protection Agency's August 2007 report to Congress on Server and Data Center Energy Efficiency(1), data centers consumed an estimated 1.5 percent of the Nation's energy in 2006 (equivalent to 61 billion Kilowatt-hours or $4.5 billion). Furthermore, the agency stated, if left unchecked, data center power consumption will threaten to cost the public and private sectors $7.4 billion in annual electricity costs by 2011.

Fully appreciating the storage-energy dilemma, each WD RE2-GP hard drive consumes an average of 4-5 watts less than competitive hard drives, making it possible for energy-conscious enterprise customers to build servers and storage subsystems with higher capacities, consistent performance, and assured reliability, all while promoting energy conservation. By WD estimates, under typical workloads, the new WD RE2-GP drives will save more than $10 per drive per year in electricity costs. Consequently, a large data center with 10,000 drives can save $100,000 in annual energy costs.

Other 1 TB hard drives typically consume power as high as 13.5 watts. Replacing these drives with WD RE2-GP hard drives will reduce overall annual energy costs, not only through the reduction of drive power consumption, but also through reduced heat and the associated expense of environmental climate controls.

"WD's RE2-GP enterprise line of hard drives allow customers to expand their storage needs, reduce their total cost of ownership, and improve the environment all at the same time," said Tom McDorman, vice president and general manager of WD's enterprise business unit. "Energy efficiency is a huge concern for our customers. GreenPower drives are enabling them to meet their customer's system requirements for storage capacity, reliability, performance, and cost by integrating an enterprise-class drive that simply consumes far less power."

Exclusive Intelligent Drive Technology
GreenPower drives from WD deliver exceptional power conservation, run ultra-cool and quiet, while providing solid performance. The following technologies enable the WD RE2-GP platform:

IntelliPower(TM) -- A fine-tuned balance of spin speed, transfer rate, and caching algorithms designed to deliver both significant power savings and solid performance. Additionally, GreenPower drives consume less current during start up allowing more drives to spin up simultaneously resulting in faster system readiness.

IntelliSeek(TM) -- Calculates optimum seek speeds to lower power consumption, noise and vibration.

IntelliPark(TM) -- Delivers lower power consumption by automatically unloading recording heads during idle to reduce aerodynamic drag and by disabling read/write channel electronics.

Active Power Management -- WD GreenPower drives monitor work load and automatically invoke idle mode whenever possible to further reduce unnecessary power consumption. Drive recovery time from idle mode is less than one second, providing seamless communication between the drive and the host controller.
