Western Digital WD1600AVBS, WD1600AVJS, WD2500AVBS, WD2500AVJB, WD2500AVJS Specifications

CE Hard Drives

• Long-Term Reliability – With a MTBF of 1 million hours, these

drives are designed to last in high temperature always-on streaming
digital audio/video environments such as PVR/DVR, DVR recorders,
and surveillance video recorders.

• Quiet – Noise levels have been minimized to less than
one sone* – virtually below the threshold of human hearing.

• Low Power, Cool Running – WD AV drives deliver best-in-class
low power consumption for reduced system power requirements
and increased reliability.

• Compatible – Tested for compatibility in a broad range of
AV products including set top boxes, DVD recorders, and
mainstream surveillance systems.

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 allowing CE customers to use standard streaming
management and error recovery options.

IntelliSeek

™ – Optimizes seek speeds to lower power consumption, noise

and vibration.

Ramp Load – Parks the recording heads off the disk surface during spin up,

spin down, and when the drive is off. This ensures the recording head never
touches the disk surface resulting in improved long term reliability due to less
head wear, and improved non-operational shock tolerance.

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.

WD AV SATA and EIDE drives are ideal for PVR/DVR, DVD recorders,
surveillance video recorders, and other video streaming applications.

*A sone is a subjective unit of loudness as perceived by a person with normal hearing.
**Assumes Host Transfer Block size of 2 MB per stream.

Designed for demanding
audio and video environments.
