5-year limited warranty. High Performance Electronics Architecture: Dual processor – Twice the processing power to maximize performance. Colossal cache – Bigger, faster cache of up to 64 MB means faster performance. Rock Solid Mechanical Architecture: 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 stabilize platters for accurate tracking, during read and write operations. NoTouch ramp...  (less)
