Western Digital AV-GP WD40EURX Hard Drive, 3.5" Form Factor, 4TB (4000GB) Capacity, 64MB Cache, SATA 6Gb/s Interface, Up to 480 Hours of HD Video, 24x7 reliability for video streaming.



24x7 reliability.

These drives are designed to last in always-on, streaming digital audio/video environments such as PVRs, DVRs and surveillance video recorders.



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



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.



Calculates optimum seek speeds to lower power consumption, noise and vibration.



Reduced power consumption.

With the combination of WD's IntelliSeek, IntelliPark, and IntelliPower technologies, WD has reduced power consumption by up to 40 percent compared to competitors' drives.



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.


Advanced Format Technology (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 models only)



Whisper quiet.

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


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.


Ideal for:

PVRs, DVRs, set-top boxes (STBs), and surveillance video recording.




Surveillance Storage from Western Digital.

Increasing security concerns have caused governments and businesses of all sizes to invest significantly in digital video surveillance systems. Created initially as a means of security for banks in the 1940s, video surveillance systems have evolved to become one of the most popular safety and security systems today.


Thanks to rapid advancement in technology, video surveillance systems have experienced exponential growth since their introduction. In recent years, video surveillance has undergone a shift from analog to digital format and away from primarily tape-based systems.


This transition has resulted in advancements in many complementary technologies. Whether it's software to aid in the recording and analysis of high resolution images, networking systems to more efficiently mirror and archive, or the emergence of technologies such as smart sensors and biometrics, today's surveillance systems demand the best performing and most reliable hard drives and solid state drives (SSD) available.



Storage designed for digital video surveillance.


Life in a desktop computer doesn't compare to the extreme environment in today's always-on, capacity-consuming digital video surveillance systems. What's needed is a drive that has been engineered to manage up to 10 simultaneous audio-video streams and welcomes the challenge of an environment that's running 24x7 while offering exceptional dollars-per-gigabyte value. That's why WD has designed a storage lineup of surveillance-based hard drives and SSDs perfect for digital video surveillance and its many unique environments and application sets.



High capacity enables higher resolution.


WD was the first to market with a 2 TB drive designed for surveillance. This ground-breaking capacity point enables surveillance systems with two or more cameras to record high levels of clarity (30 frames per second) at a broad range of resolution settings and still store 30 days or more of video footage. Using high-capacity surveillance drives will become even more important as HD becomes increasingly pervasive. High resolution video provides far greater detail when compared to standard low resolution video.



WD's surveillance drives enable digital video surveillance systems to deliver a comprehensive range of features and capabilities such as high resolution image quality, streaming video from multiple cameras, video archiving with ultra-fast data access and on-demand video playback.




Lower temperature means greater reliability.

In addition to high levels of clarity, long-term reliability and low-power consumption are equally critical to surveillance systems. Designed for 24x7 operation, WD drives with WD GreenPower Technology™ consume less power during spin-up and operation, minimize heat dissipation and vibration, and operate reliably without compromising performance. Reducing heat, noise, and vibration enables surveillance applications to operate more reliably over longer periods of time.
