The Deskstar P7K500
Hitachi Global Storage Technologies has implemented a set of power-saving technologies to reduce the Deskstar P7K500's active and idle power consumption by up to 40 percent over the previous generation. With idle power utilization of 4.8 watts (3.6 watts on the 250-GB capacity model) and active power requirements of 8.2 watts (6.4 watts for the one-disk model), the P7K500 utilizes just over half of the idle power typically allotted to hard drives in Energy Star-rated PCs.
