• 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.
