WD Caviar Black Desktop Hard Drives - WD Maximum Performance for Power Computing
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.
Maximum Performance
Dual processor technology, up to 64 MB cache and SATA 3 Gb/s or 6 Gb/s interface takes everything we know about 7200 RPM performance and turns it on its ear.
No Compromises
High performance, high capacity, best-in-class reliability, and cutting edge technology make up WD Caviar Black, the ideal drive for those who demand only the best.
Award Winning
This 7200 RPM speedster is at the top of its class when it comes to performance and reliability benchmarks.
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. (2TB 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.

1 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 per 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 transfer rate 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.
2 WD hard drive products manufactured and sold worldwide after June 1, 2006, meet or exceed Restriction of Hazardous Substances (RoHS) compliance requirements as mandated by the European Union for electrical and electronic products. The RoHS Directive 2002/95/EC of the European
Parliament, which is effective in the EU beginning July 1, 2006, aims to protect human health and the environment by restricting the use of certain hazardous substances in new equipment, and consists of restrictions on lead, mercury, cadmium, and other substances.
