GreenPower for AV:

Cool. Quiet. Reliable.

Power-conserving WD AV-GP SATA hard drives take advantage of WD’s

GreenPower ™ technology to meet the extreme requirements of demanding

audio and video environments. With power reduction of up to 40%, they

deliver cool and quiet operation and reliability perfect for audio video

applications such as PVRs, DVRs, set-top boxes (STBs) as well as

surveillance video recording.

Ideal for set top boxes, media

servers, media centers, and

mainstream surveillance systems.

• Long-Term Reliability – These drives are designed to last in high

temperature, always-on, streaming digital audio/video environments.

• Reduced Power Consumption – WD has reduced power

consumption by up to 40 percent compared to competitors’ drives

with the combination of WD’s IntelliSeek ™ , IntelliPark ™ , and

IntelliPower ™ technologies.

• Quiet – Noise levels have been optimized to less than one sone* – virtually

below the threshold of human hearing.

Technology Features

SilkStream ™ – Optimized for smooth, continuous digital video playback of up to

twelve simultaneous HD streams. SilkStream is compatible with the ATA streaming

command set so CE customers can use standard streaming management and error

recovery options.

IntelliSeek – Calculates optimum seek speeds to lower power consumption, noise,

and vibration.

IntelliPower – A fine-tuned balance of spin speed, transfer rate, and caching algorithms

designed to deliver both significant power savings and solid performance.

IntelliPark – Delivers lower power consumption by automatically unloading the heads

during idle to reduce aerodynamic drag.

Preemptive Wear Leveling (PWL) – The drive arm frequently sweeps across the disk to

reduce uneven wear on the drive surface common to audio video streaming applications.

*A sone is a subjective unit of loudness as perceived by a person with normal hearing.
