Architecture
Dual actuator technology
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)
We perform tests on hundreds of
systems and a multitude of platforms
in our FIT Lab™ and Mobile
„
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)
Dual processor — Twice the
processing power to maximize
performance.
Compatibility Lab to give our
„
customers confidence that our drives
will work in their systems.
Colossal cache — Bigger, faster
cache of up to 64 MB means faster
performance.
5-year limited warranty
„
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.
Massive Capacity
WD Caviar Black SATA drives are
available in capacities up to 2 TB.
Applications
„
Power computing applications such as multimedia, video and photo editing, and maxed out gaming computers.
„
Desktop / Consumer RAID Environments - WD Caviar Black Hard Drives are tested and recommended for use in consumer-type RAID applications (RAID-0 /
RAID-1).
- Business Critical RAID Environments – WD Caviar Black Hard Drives are not recommended for and are not warranted for use in RAID environments utilizing Enterprise HBAs and/or
expanders and in multi-bay chassis, as they are not designed for, nor tested in, these specific types of RAID applications. For all Business Critical RAID applications, please consider WD’s
Enterprise Hard Drives that are specifically designed with RAID-specific, time-limited error recovery (TLER), are tested extensively in 24x7 RAID applications, and include features like
enhanced RAFF technology and thermal extended burn-in testing.

1As 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 and SATA 6 Gb/s transfer rates calculated according to the Serial ATA specification
2WD 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.
