The WD Caviar Black 2TB SATA Hard Drive (OEM), with high-performance dual actuator technology provides an optimum storage solution for a fully-loaded PC or a maxed out gaming machine. The primary actuator offers coarse displacement using conventional electromagnetic actuator principles and the secondary actuator uses a piezoelectric motor to fine tune the head positioning to a higher degree of accuracy.
A featured motor shaft on both ends minimizes the system-induced vibration and stabilizes platters for accurate tracking, during read and write operations. The NoTouch Ramp Load technology ensures that the recording head never touches the disk media, providing enhanced drive protection in transit. With 64MB cache, the Caviar Black SATA Hard Drive ensures faster data transactions by reducing the time required for data transactions.
