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.

Data security option
Deskstar 7K1000.B features optional Bulk Data Encryption (BDE) that uses an Advanced Encryption Standard (AES) certified by the National Institute of Standards and Technology (NIST) to deliver the strongest commercially available data security protection. Data is scrambled using a key as it is written to the disk then descrambled with the key as it is retrieved. BDE also speeds and simplifies the drive re-deployment process. By deleting the encryption key, the data on the drive is rendered unreadable, thereby eliminating the need for time-consuming data-overwrite.
