WD Caviar® Black
Desktop Hard Drives
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. And we
back it all up with a 5-year limited warranty.

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.
