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

Reduced power consumption — WD has reduced power consumption by up to 40 percent

compared to standard desktop drives with the combination of WD's IntelliSeek™, NoTouch™,

and IntelliPower™ technologies.

Helps enable eco-friendly PCs — By using environmentally-conscious PCs with our

WD Caviar Green drives on board, large organizations with many desktop computers can

minimize their carbon footprint and save real money on electricity costs.

Cool and quiet — WD GreenPower Technology™ yields 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.

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 model only)

Native Command Queuing (NCQ) — Server feature for performance in random I/O

transaction environments. It aggregates many small random data transfers and allows the disk

to reorder the commands in a sequential order for faster access.

Perpendicular Magnetic Recording (PMR) — Employs PMR technology to achieve even

greater areal density.

Low power spin-up — WD Caviar Green drives consume less current during startup allowing

lower peak loads.

Advanced power technology — Electronic components deliver best-in-class low power

consumption for reduced power requirements and increased reliability.

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

2 WD hard drive products manufactured and sold worldwide after June 1, 2006, meet or exceed Restriction of Hazardous Substances (RoHS)

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.
