Hard Drive Western Digital 750GB WD7502AAEX 64MB SATA III 7200 RPM 3.5" Inch

Dual processor - twice the processing power to maximise performance Colossal cache - bigger, faster cache of up to 64Mb means faster performance Dual actuator technology - a head positioning system with two actuators that improves positional accuracy over the data track(s). The primary actuator provides coarse displacement using conventional electromagnetic actuator principles. The secondary actuator uses piezoelectric motion to fine tune the head positioning to a higher degree of accuracy StableTrac - the motor shaft is secured at both ends to reduce system-induced vibration and stabilise platters for accurate tracking, during read and write operations NoTouch ramp load technology - the recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit
