Western Digital WD10EVCS User manual

• 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.
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.

GreenPower for AV:
Cool. Quiet. Reliable.
CE Hard Drives
Ideal for set top boxes, media
servers, media centers, and
mainstream surveillance systems.
*A sone is a subjective unit of loudness as perceived by a person with normal 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.
