Western Digital Power-saving Hard Drives
Western Digital GreenPower (WD AV-GP) 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, these hard drives are ideal for 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 video surveillance systems.
Compatible
Tested for compatibility in a broad range of Lorex recorders 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.
* A sone is a subjective unit of loudness as perceived by a person with normal 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/EUCX/AURS/AUDX models only)
1 million hours MTBF
Best-in-class reliability for mainstream 3.5-inch form-factor AV storage.**
** Based upon dual tuner system operating in typical 30°C air ambient environment.

- As used for storage capacity, one megabyte (MB) = one million bytes, one gigabyte (GB) = one billion bytes, and one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment. As used for buffer or cache, one megabyte (MB) = 1,048,576 bytes. As used for transfer rate or interface, megabyte per second (MB/s) = one million bytes per second, and gigabit per second (Gb/s) = one billion bits per second. Effective maximum SATA 6 Gb/s transfer rate calculated according to the Serial ATA specification published by the SATA-IO organization as of the date of this specification sheet.
- WD hard drive products manufactured and sold worldwide after June 1, 2006, meet or exceed Restriction of Hazardous Substances (RoHS) compliance requirements as mandated by the RoHS Directive 2011/65/EU.
- Controlled unload at ambient condition.
- No non-recoverable errors during operating tests or after non-operating tests.
