CoolSpin design for desktop computers The Deskstar 5K1000 hard drive provides up to a generous 1TB capacity and features innovative CoolSpin technology to deliver a new level of power efficiency and quiet operation for energy-conscious computers. Key to CoolSpin technology is an optimization of motor speed to provide an ideal balance of performance, power utilization and acoustics. The CoolSpin technology, along with other Hitachi power management techniques, gives the Deskstar 5K1000 its 25% power savings over the Deskstar 7K1000.C. With low power, capacity and cool operation, the 3.5-inch Deskstar 5K1000 enables a new generation of personal computers. Power efficient for cooler operation and longer life CoolSpin and HiVERT technologies combine to create this new class of hard drive that delivers best-of-breed power utilization and thermal emissions. HiVERT technology, pioneered on Hitachi 2.5-inch drives, helps efficiently manage power consumption. These innovations, together with eighth-generation Advanced Power Management, make the Deskstar 5K1000 the ideal choice for energy-efficient PCs that run cooler, require less power and last longer. The Deskstar 5K1000 delivers the lowest power profile of the Hitachi Deskstar family of hard drives to enable the biggest reduction in overall system power requirements, which helps PC manufacturers achieve ENERGY STAR ratings. ENERGY STAR 5.0 are specifications released by the U.S. Environmental Protection Agency (EPA) to enable energy-efficient designs for PCs and other computer equipment.
