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 a
  piezoelectric motor to fine tune the head positioning to a higher degree of accuracy. (2 TB and 1.5 TB models only)
   
• 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. (2 TB and 1.5 TB models only)
   
• 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.

 

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.

 

Massive Capacity

• WD Caviar Black SATA drives are available in capacities up to 2 TB.

 

Compatible

• 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.
