Product Features
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.
WIDTH/HEIGHT
3.5-inch/1-inch
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 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. (750 GB, 1 TB, and 2 TB models only)
NoTouch ram p l oad te ch nol og y 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.
ROTATIONAL SPEED
7200 RPM
Massive Capacity
WD Caviar Black SATA drives are available in capacities up to 2 TB.
5-year limited warranty
CAPACITIES
500 GB to 2 TB
Note: Not all products may be available in all regions of the world.
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.

As used for storage capacity, one megabyte (MB) = one million bytes , one gigabyte (GB) = one billion bytes, and one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment. As used for buffer or cache, one megabyte (MB) = 1,048,576
bytes. As used for transfer rate or interface, megabyte pe r second (MB/s) = one million bytes per second, and gigabit per second (Gb/s) = one billion bits per second. Effective maximum SATA 3 Gb/s and SATA 6 Gb/s transfer rates calculated according to the Serial ATA specification published by the SATA-IO organization as of the date of this specification sheet. Visit www.sata-io.org for details.
