1TB capacity, fewer parts

The Deskstar™ 7K1000.D is Hitachi’s rst one-disk, 1TB, 7200 RPM 3.5-inch hard drive for
use in power-friendly consumer and commercial desktop computers. This fourth-generation
1TB hard drive from Hitachi uses Advanced Format, which increases the sector size on HDDs
from 512 bytes to 4096 (4K) bytes, thereby increasing capacities and improving error correct­ing capabilities. Consult the Hitachi Advanced Format Technology Brief for more information
on these drives. 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 Hitachi, this new desktop drive provides up to 16% 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.D demonstrates Hitachi’s ecological leadership with its halogen-free
design and power-efcient operation. Both these features helped qualify the drive for the
Hitachi EcoTrac classication, which identies products that minimize environmental impact
in the areas of product design, manufacturing, operation and disposal.

Power efficiency supports ENERGY STARTM 5.0

The ENERGY STAR 5.0 specications released by the U.S. Environmental Protection Agency
(EPA) are recognized around the world as a way of identifying energy-efcient 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 prole of
the Deskstar 7K1000.D hard drive enables a reduction in overall system power requirements,
which helps PC manufacturers achieve ENERGY STAR ratings.
