Hitachi Deskstar P7K500
Energy-efficient storage for power-friendly PCs

Balanced power and performance for desktop computing

The Deskstar™ P7K500 hard drive provides an exceptional blend of power efficiency and performance making it an ideal solution for consumer and enterprise power-friendly PCs. Leveraging sixth-generation power management technology as well as power-saving innovations pioneered on Hitachi’s popular 2.5-inch line of notebook PC hard drives, this new breed of desktop drive delivers best-in-class power management and thermal emissions to help manufacturers meet energy compliance targets and extend drive life.

Power efficiency helps manufacturers deliver ENERGY STAR® 4.0 compliant systems

The ENERGY STAR 4.0 specifications are recognized around the world as a way of identifying energy-efficient PCs and other office equipment. PCs that meet the ENERGY STAR 4.0 criteria are expected to become increasingly required by government agencies, corporations and consumers. Some corporations are choosing to purchase ENERGY STAR PCs as part of their “green” initiatives. The Deskstar P7K500 hard drive delivers industry-leading low-power consumption – up to 40 percent operational power savings over previous generation products – contributing to a reduction in overall system power requirements which helps PC manufacturers achieve ENERGY STAR ratings. Additionally, less power required by the hard drive means more power budget available in an ENERGY STAR PC for additional features and functions.

Robust technology and configuration flexibility

Featuring a Serial SATA interface to meet the needs of many design configurations, the Deskstar P7K500 is also built using the industry’s most reliable perpendicular magnetic recording (PMR) techniques to maximize capacity, performance and field reliability.

Highlights

  • Up to 40 percent operational power savings over previous generation products
  • Capacities up to 500GB ¹
  • Built on industry’s most reliable PMR technology

Applications

  • Consumer & commercial computers
  • Personal storage
  • PC gaming
