    WD Purple Surveillance Hard Drive

    Uncompromising Surveillance Storage

     

    WD Purple drives are designed to meet the challenges of 24x7 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 that’s tested for compatibility in a wide range of security systems. Exclusive AllFrame™ technology helps reduce frame loss and improve overall video playback.

     

    Industry-Leading Storage. Surveillance You Can Trust

    Western Digital has provided surveillance-grade storage for more than a decade. With WD Purple surveillance storage, drives are engineered for high temperature, always-on surveillance systems so you can rely on quality video when you need it most.

    Western Digital's Exclusive AllFrame™ Technology

    All WD Purple drives are equipped with AllFrame™ technology, which helps reduce video frame drops and improves video recording and playback.

    Enhanced Workload Ratings

    WD Purple drives feature a workload rating of up to 180TB/year - up to three times that of desktop drives - to handle the unique demands of mainstream video surveillance DVR and NVR systems.

     

     

    Multiple Cameras, Multiple Streams

    Modern recorders now support multiple video streams per camera. WD Purple drives support up to 64 single-stream HD cameras. With so many options, you have the flexibility to upgrade or expand your security applications in the future.

    Designed for Surveillance Solutions

    With an MTBF of up to 1 million hours, WD Purple drives are engineered for mainstream surveillance DVRs and NVRs that operate 24/7. With tarnish-resistant components and support in storage systems with more than eight drive bays, WD Purple drives deliver reliable operation even in harsh environments.

    Wide Compatibility. Seamless Integration

    WD Purple hard drives are built with compatibility in mind, so you can quickly and seamlessly add capacity to your surveillance system. With a wide range of industry-leading enclosures and chipsets supported, you’re sure to find the DVR or NVR configuration that’s right for you.
