Less Power, More Performance
The Deskstar™ 7K1000.C hard drive is a 7200 RPM 3.5-inch hard drive that provides an
exceptional blend of power efficiency and performance, making it an ideal solution for
power-friendly consumer and commercial desktop computers. This third-generation 1TB
hard drive from HGST boosts media transfer rate performance by as much as 13% over
its predecessor. Leveraging eighth-generation power management technology, as well as
power-saving HiVERT™ innovations pioneered on the popular 2.5-inch line of notebook hard
drives from HGST, this new desktop drive provides up to 18% idle power savings over the
previous model, delivering best-in-class power management and thermal emissions.
Innovation for a More Sustainable Environment
The Deskstar 7K1000.C demonstrates HGST's ecological leadership with its halogen-free
design and power-efficient operation. Both these features helped qualify the drive for the
HGST EcoTrac classification, which identifies products that minimize environmental impact
in the areas of product design, manufacturing, operation and disposal.
Power Efficiency Supports ENERGY STAR
The ENERGY STAR 5.0 specifications released by the U.S. Environmental Protection Agency
(EPA) are recognized around the world as a way of identifying energy-efficient PCs and
other computer equipment. PCs that meet the ENERGY STAR 5.0 criteria are expected to
become increasingly popular with both corporations and consumers. Some corporations are
choosing to purchase ENERGY STAR PCs as part of their "green" initiatives. The low power
profile of the Deskstar 7K1000.C hard drive enables a reduction in overall system power
requirements, which helps PC manufacturers achieve ENERGY STAR ratings.
