Product Features
Reduced power consumption
WD has reduced power consumption
by up to 40 percent compared to
standard desktop drives.
Environmentally responsible
WD Caviar Green drives yield an

designed to deliver both significant
power savings and solid performance.
Calculates optimum seek speeds to
lower power consumption, noise, and
NoTouch™ ramp load
Low power spin-up
The recording head never touches
the disk media ensuring better
drive protection in transit as well as
significantly less wear to the recording
head and media.
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
models only)
WD Caviar Green drives consume less
current during startup allowing lower
peak loads.
Advanced power technology
Electronic components deliver bestin-class low power consumption for
reduced power requirements and
increased reliability.

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 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.
