Less power, more performance
The DeskstarTM 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 Hitachi boosts media transfer rate performance by as much as 13% over its predecessor.
Leveraging eighth-generation power management technology, as well as power-saving
HiVERTTM innovations pioneered on the popular 2.5-inch line of notebook hard drives from
Hitachi, 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 Hitachi's ecological leadership with its halogen-free
1TB, 750, 640, 500, 320,
design and power-efficient operation. Both these features helped qualify the drive for the
250 and 160GB
Hitachi EcoTrac classification, which identifies products that minimize environmental impact
7200 RPM | SATA 3Gb/s
in the areas of product design, manufacturing, operation and disposal.
Power efficiency supports ENERGY STARTM 5.0
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.
