2.5-inch Drive

24x7 reliability.
Reliable performance engineered for demanding always-on multimedia streaming environments.

Low-power, compact storage.
Cool, quiet 2.5-inch AV storage is the perfect solution for a variety of multimedia applications and fanless environments where the drive operates below 65° C base casting temperature.

Supports high definition video.
SilkStream technology supports up to five simultaneous streams of HD video in a variety of file formats.
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.
SilkStream technology.
Optimized for smooth, continuous digital video playback of up to five simultaneous HD streams. SilkStream is compatible with the ATA streaming command set so AV customers can use standard streaming management and error recovery options.
Quiet.
Noise levels have been minimized to less than one sone* - virtually below the threshold of human hearing.
Low power consumption.
The drive draws less than 2 Watts while operating and a mere 4.75 Watts during spin up.
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.
** Based upon dual tuner system operating in typical 30°C air ambient environment.
1 million hours (MTBF).
Best-in-class reliability for small-form factor AV storage.**
Ultra-cool operation.
A cool drives is a more reliable drive. WD continues to develop new and innovative ways to keep drives cool while they are operating.
Ideal for:
Video surveillance, DVRs/PVRs, set-top boxes, high-end audio systems, karaoke players and digital signage.

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.

Examples of the number of photos, songs, videos and any other files that can be stored on a hard drive are provided for illustrative purposes only. Your results will vary based on file size and format, settings, features, software and other factors.

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.
