Hitachi Deskstar P7K500 Worlds most energy efficient desktop hard disk drive

Hitachi GST has implemented a set of power-saving technologies to reduce the P7K500’s active and idle power consumption by up to 40 percent over the previous generation. As a result, the Hitachi P7K500 achieves best-of-breed power consumption on its one-disk model and significant power savings on its two-disk model, both with 7200 RPM performance and Serial-ATA interface. Hitachi GST’s new hard drive is designed for commercial and consumer PCs in capacities ranging from 250GB to 500GB. The Hitachi P7K500 is up to 59 percent more power efficient than comparable 250GB hard drives in its class, based on available specifications. The Hitachi P7K500 incorporates Hitachi GST’s second-generation perpendicular magnetic recording (PMR) heads and disks, enabling 250GB-per-platter areal density and ensuring a high level of reliability. Built using Hitachi GST’s sixth-generation power management technology, as well as other new energy innovations, the Deskstar P7K500 represents a significant decrease in power consumption over its predecessor as well as competitive hard drives in its class.
