WD Caviar Black drives combine a high performance electronics architecture with a rock solid mechanical architecture to deliver the perfect storage solution for your fully loaded PC or maxed out gaming machine. Cool drive operation, no touch head technology, leading edge vibration protection ensure enhanced reliability. WD Caviar Black Dual actuator technology 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 a piezoelectric motor to fine tune the head positioning to a higher degree of accuracy (2 TB only). With WD Caviar Black StableTrac Technology the motor shaft is secured at both ends to reduce system induced vibration and stabilize platters for accurate tracking, during read and write operations (750 GB, 1 TB, and 2 TB models only). No Touch 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. We perform tests on hundreds of systems and a multitude of platforms in our FIT Lab and Mobile Compatibility Lab to give our customers confidence that our drives will work in their systems.
