Green Power for AV: Cool, quiet, reliable.

Power-conserving WD AV-GP drives offer significant power savings and thermally optimized operation resulting in lower cost of ownership and unsurpassed reliability for PVR/DVR, IPTV boxes and media server manufacturers. Now with a broad range of capacity points from 160GB all the way up to 2TB.

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

Product Features

Long-Term Reliability - 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. 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. Compatible - Tested for compatibility in a broad range of AV products including set top boxes, DVD recorders, and mainstream surveillance systems. 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. View demo >  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.
