Interface:
SAS 6 Gb/s

Industry’s highest capacity nearline drive.
WD RE SAS hard drives are available in capacities ranging from 1 TB to 4 TB to suit even the most demanding storage needs.

Highest performance for business-critical applications.
WD RE delivers 6 Gb/s transfer rates, sustained sequential data rates of up to 182 MB/s and high random I/O rates.

Designed for quality and reliability.
With a 1.4 million hour MTBF, this high performance drive delivers the highest level of reliability for 24x7 operation in up to 100% duty cycle applications.
Dual port, full duplex connectivity.
Offers higher reliability, performance and data availability by eliminating single points of failure, designed for leading business-critical Enterprise topologies.
Environmentally conscious.
In addition to being RoHS compliant, WD RE is built with halogen-reduced components.
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.
Dual stage actuator technology.
A head positioning system with two actuators that improves positional accuracy over the data track(s). The primary actuator provides coarse displacement using conventional electromagnetic actuator principles. The secondary actuator uses piezoelectric motion to fine tune the head positioning to a higher degree of accuracy.
RAFF.
Enhanced RAFF technology includes sophisticated electronics to monitor the drive and correct both linear and rotational vibration in real time. The result is a significant performance improvement in high vibration environments over the previous generation of drives.
RAID-specific, time-limited error recovery (TLER).
Prevents drive fallout caused by the extended hard drive error-recovery processes common to desktop drives.
Ultra compatible.
An ultra-fast 6 Gb/s SAS interface enables easy integration into SAS storage subsystems while delivering twice the interface speed of traditional 3 Gb/s SAS nearline hard drives.
The WD advantage.
WD puts our products through extensive Functional Integrity Testing (F.I.T) prior to any product launch. This testing ensures our products consistently meet the highest quality and reliability standards of the WD brand. WD also has a detailed Knowledge Base with more than 1,000 helpful articles as well as helpful software and utilities. Our customer support lines have longer operational hours to ensure you get the help you need when you need it. Our toll-free customer support lines are here to help or you can access our WD Support site for additional details.
Ideal for:
High-capacity data center storage, demanding high-performance computing, business-critical environments, storage area networks (SAN), network attached storage (NAS), direct attach storage (DAS), networked surveillance systems and cloud storage.


The chipsets, host adapters, RAID controllers, enclosures and Operating Systems listed in the compatibility summary have been tested with WD drives for data integrity, interoperability, and compatibility, and any special conditions observed are noted.

Surveillance Storage from WD.


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.

 

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.

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.

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.
 

The right drive for every surveillance application.


WD offers a full range of drives with the features and reliability the surveillance market demands.
  
WD AV-GP surveillance hard drives deliver smooth, continuous playback of up to 12 HD multimedia streams, perfect for mainstream surveillance for small businesses.

Compatibility

  • Windows 7/Vista/XP/2000, Windows server, Linux, and Mac OS.

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, megabit per second (Mb/s) = one million bits per second, and gigabit per second (Gb/s) = one billion bits per second.
