1TB capacity, fewer parts  
The Deskstar™ 7K1000.D is Hitachi’s first 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 correct-  
ing 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.  
1TB, 750, 500, 320 and 250GB  
7200 RPM | SATA 6Gb  
Innovation for a more sustainable environment  
The Deskstar 7K1000.D demonstrates Hitachi’s ecological leadership with its halogen-free  
design and power-efficient operation. Both these features helped qualify the drive for the  
Hitachi EcoTrac classification, which identifies products that minimize environmental impact  
in the areas of product design, manufacturing, operation and disposal.

Power efficiency supports ENERGY STAR 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.D hard drive enables a reduction in overall system power requirements,  
which helps PC manufacturers achieve ENERGY STAR ratings.
