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.

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.
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

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.
