Low power consumption WD AV drives deliver best-in-class low power consumption for reduced system power requirements and increased reliability.

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.

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

IntelliSeek Calculates optimum 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.

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

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.

Ideal for PVR/DVR, DVR recorders, and surveillance video recorders.
