320GB HGST Deskstar™ 7K1000.C
Energy-efficient storage for power-friendly PCs

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 powerfriendly consumer and commercial desktop computers. This third-generation 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 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.

  1. One GB is equal to one billion bytes and one TB equals 1,000GB (one trillion bytes) when referring to hard drive capacity.. Accessible capacity may be less.
  2. Portion of buffer capacity used for drive firmware
  3. Intended for low duty cycle, non mission-critical applications in PC, nearline, and consumer electronics environments, which may vary from application to application. Note that customer environments may vary from application to application.

Specific application environments such as temperature and duty cycle will affect the overall reliability rates.
