WD Purple drives are designed to meet the challenges of 24×7 video surveillance recording. These drives are engineered specifically for surveillance to help withstand the elevated heat fluctuations and equipment vibrations within NVR environments. An average desktop drive is built to run for only short intervals, not the harsh 24/7 always-on environment of a high-definition surveillance system. With WD Purple drives, you get reliable, surveillance-class storage thats tested for compatibility in a wide range of security systems. Exclusive AllFrame technology helps reduce frame loss and improve overall video playback.

Choose a drive that is designed and engineered for home and business surveillance systems and enjoy the peace-of-mind you can only get from a surveillance-class hard drive.

Desktop drives vs. surveillance-class storage

You wouldnt use a bicycle to transport cargo across the country because its not the right tool for the job. You also shouldnt use a desktop hard drive in your surveillance security system because it wasnt designed for that application.

WD Purple surveillance-class storage has been tested to be compatible in a wide-range of security systems. These drives are designed to replace standard desktop drives that were not designed for the harsh 24/7 always-on, high-definition surveillance environment. Desktop drives are built to run for only short intervals and are not engineered to withstand high-temperature fluctuations and equipment vibrations found in a typical surveillance application.

Surveillance storage for peace-of-mind
Whether youre protecting your personal assets and loved ones or monitoring the business you worked hard to build, you can rely on surveillance-class storage built by one of the largest hard drive manufacturers in the world. WD Purple Surveillance Storage is designed for high temperature, always-on, surveillance security systems to ensure reliability and quality video play back when you need it most. Experience the security of knowing youre using a surveillanceclass drive designed by a leader in the hard drive industry.

Improve performance with AllFrame
WD Purple surveillance-class hard drives are equipped with AllFrame technology which works with ATA streaming to reduce frame loss, improve playback and increases the number of drive bays supported. AllFrame reduces video interruptions that commonly occur when desktop hard drives are incorrectly used as storage in security systems. Missed frames and lost footage is a serious problem when an event occurs and surveillance footage needs to be retrieved. WD Purple with AllFrame provides the confidence you should expect when its time to play back and review critical surveillance footage.

Key benefits:

Reduces video frame loss with surveillance-class storage.
Specifically tuned for surveillance security systems.
Caching algorithms are tuned for write-intensive, low bit rate, high stream count applications that are typical of surveillance applications.
