 Well, that’s what Hitachi’s claiming. Their new Deskstar P7K500 desktop hard drive reduces the active and idle power consumption by up to 40 percent over the previous generation, and satisfied certification standards for Energy Star 4.0. Coming in both a one-disk and two-disk model, the new hard drive is designed for commercial and consumer PCs in capacities ranging from 250GB to 500GB.
The Hitachi P7K500’s reduction in active power requirements to 6.4 watts and 8.2 watts for its one- and two-disk models respectively, is certainly an improvement, but the big gain (or actually loss, I guess) is in its idle power utilization of 3.6 watts on the 250GB capacity model and 4.8 watts on models with capacities of 320GB or greater. With 7 watts of idle power typically allocated for hard drives, PCs using the Hitachi drive should be able to budget more power margin for additional high-value features or to reduce overall power requirements.
“The development of ‘green’ computing products that comply with energy-rating programs, such as ENERGY STAR 4.0, is becoming an extremely important initiative for our customers,” said Shinjiro Iwata, executive vice president, Hitachi Global Storage Technologies. “With the Deskstar P7K500 hard drive, we have merged our various power management innovations into one drive, achieving leading power specifications that make a positive contribution to system power consumption.”
