WD Caviar® Green™

Desktop Hard Drives

As hard drive capacities increase, the power required to run

those drives increases as well. WD Caviar Green drives

make it possible for energy-conscious customers to build

systems with higher capacities and the right balance of

system performance, ensured reliability, and energy

conservation.

Massive capacity
WD Caviar Green SATA drives now
deliver up to 3 TB of storage on a
single drive.
Reduced power consumption
WD has reduced power consumption
making it possible for our energy-
conscious customers to build systems
with higher capacities and the right
balance of system performance,
ensured reliability, and
energy conservation.
Cool and quiet
Drives with WD GreenPower
Technology™ yield lower operating
temperatures for increased reliability
and low acoustics for ultra-quiet PCs
and external drives.
Perfect for external drives
External drive manufacturers can
eliminate the need for a fan in a
high-capacity product with a
WD Caviar Green drive, the coolest
and quietest in its class.
IntelliPower
A fine-tuned balance of spin speed,
transfer rate, and caching algorithms
designed to deliver both significant
power savings and solid performance.
Additionally, WD Caviar Green drives
consume less current during startup
allowing lower peak loads on systems
as they are booted.
IntelliSeek™
Calculates optimum seek speeds to
lower power consumption, noise,
and vibration.
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.
Advanced Format (AF)
Technology being adopted by WD and
other drive manufacturers as one of
multiple ways to continue growing
hard drive capacities. AF is a more
efficient media format that enables
increased areal densities. (RX, DX, and
RS models only)

Desktop / Consumer RAID Environments - WD Caviar Green Hard Drives are tested and recommended for use in consumer-type RAID applications (RAID-0 /
RAID-1).
-Business Critical RAID Environments – WD Caviar Green 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.
