WESTERN DIGITAL Caviar Green 640GB WD6400AADS

Hard drives using perpendicular technology write-sized 640 gigabytesThis technology allows you to write data vertically on the disk platter, data record is so dense and capacity several times higher than normal longitudinal registration.The buffer ensures top-Job response times and processing video, audio, graphics or computer games.Mark Green Power means breakthrough technology hard drives, which reduces operating consumption.Ried out by saving features IntelliPower, IntelliPark and Intelliseek.The first of these synchronizes speed of disk platters, transfer rate and caching to save disk consumption and optimum performance.IntelliPark automatically parks the disk heads and Intelliseek, which calculates the optimal interplay between headers and the plates for optimal consumption.These features save disk stamina and the environment.
