Energy-efficient storage for power-friendly PCs

Balanced power and performance for desktop computing

The DeskstarTM 7K1000.B hard drive provides an exceptional blend of power efficiency and performance making it an ideal solution for power-friendly consumer and commercial PCs. Leveraging seventh-generation power management technology as well as power-saving innovations pioneered on the popular 2.5-inch line of notebook hard drives from Hitachi, this new breed of desktop drive delivers best-in-class power management and thermal emissions, while maintaining high standards of performance.

Energy efficiency helps manufacturers deliver ENERGY STAR 4.0 compliant systems

The ENERGY STAR 4.0 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 4.0 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 Deskstar 7K1000.B hard drive delivers industry-leading low-power consumption—up to 43% idle power savings over previous generation products—contributing to 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.
