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.

Product Features
Massive capacity
Cool and quiet
IntelliPower
WD Caviar Green SATA drives now
deliver up to 3 TB of storage on a
single drive.
Drives with WD GreenPower
Technology™ yield lower operating
temperatures for increased reliability
and low acoustics for ultra-quiet PCs
and external drives.
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.
Reduced power consumption
WD has reduced power consumption
making it possible for our energyconscious customers to build systems
with higher capacities and the right
balance of system performance,
ensured reliability, and
energy conservation.
Perfect for external drives
External drive manufacturers can
eliminate the need for a fan in a highcapacity product with a
WD CaviarGreen drive, the coolest and
quietest in its class.
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. (RS and
RSDTL models only)
Applications
„
„
Desktop PCs, high capacity external storage, and NAS.
Desktop / Consumer RAID Environments - WD Caviar Green Hard Drives are tested and recommended for use in consumer-type RAID applications (i.e., Intel
Matrix RAID technology).
- 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.

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 SATAIO organization as of the date of this specification sheet. Visit www.sata-io.org for details.
