WD AV-GP
Video and Surveillance Drives
WD AV-GP SATA hard drives store more hi-def audio and video than ever before – up to 3 TB. They are optimized with SilkStream™ technology to capture data from up to 12
simultaneous HD video streams. And with 24x7 operation, low temperature, and best-in-class reliability, WD AV-GP hard drives are ideal for DVR/PVR and video surveillance
applications.
Highest capacity for audio/video storage
WD AV-GP SATA drives now offer unrivaled storage capacity up to 3 TB – perfect for today’s storage intensive applications.
24x7 reliability
These drives are designed to last in high temperature always-
on streaming digital audio/video environments such as PVR/DVR, IPTV, and video surveillance systems.
Reduced power consumption
WD AV-GP drives consume less power by up to 40 percent compared to 7200 RPM hard drives. Lower power means less heat and greater reliability.
Quiet
Noise levels have been minimized to less than one sone* - virtually below
the threshold of human hearing.
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.
NoTouch™ ramp load technology
The recording head never touches the disk media ensuring significantly
less wear to the recording head and media as well as better drive protection in transit.
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.
Advanced Format (AF)
Technology being adopted by WD and other drive manufacturers as one
of multiple ways to continue growing hard drive capacities. AF is a more efficient media format that enables increased areal densities. (EURS/EURX/AUDX models only)
