    WD Purple Surveillance 4 TB Internal HDD - WD40PURZ Product Description

    The Right Drive for The Right Job
    WD Purple™ drives have been engineered specifically for surveillance, so they're able to 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. A disruption to a drive could result in a failure that impacts multiple users, your security archive, or even the entire system. With WD Purple™, you get reliable, surveillance-class storage that's tested for compatibility in a wide-range of security systems.

    Industry-Leading Storage. Surveillance You Can Trust
    WD is a worldwide leader in the hard drive industry. With WD Purple™ surveillance storage, you have a drive engineered for high temperature, always-on surveillance systems so you can rely on quality video playback when you need it most. Whether you're protecting loved ones or monitoring your business, WD Purple™ offers performance you can trust.

    Trust Your View with AllFrame 4K™ Technology
    Missed frames and lost footage could be a serious problem when video surveillance needs to be retrieved. All WD Purple™ drives are equipped with AllFrame 4k™ technology, which improves ATA streaming to help reduce frame loss, improve overall video playback, and increase the number of hard drive bays supported within a NVR. Help make your surveillance solution future-ready knowing that WD Purple™ drives are ready for ultra-high definition cameras.

    Enhanced Workload Rating
    With a workload rating* of 180 TB/yr - three times that of desktop drives - WD Purple is designed to handle the unique demands of modern video surveillance DVR and NVR systems.

    Expand Your View to 64
    Each WD Purple™ drive is optimized to support up to 64 cameras. With so many options, you have the flexibility to upgrade or expand your security system in the future.

    Designed for Today's and Tomorrow's Surveillance Solutions
    Engineered for 24/7 operation in all sizes of mainstream surveillance DVRs and NVRs. With support for more than eight bays** and tarnish resistant components**, WD Purple drives deliver reliable operation in larger scale surveillance systems in harsher environments.

    Field-Proven High Capacity
    Now on its 4th generation and with more than 12 million drives shipped (as of Dec 2016), field-proven HelioSeal™ Technology delivers trusted high-capacity WD Purple storage (8TB and 10TB) for the massive storage needs of 4K surveillance video

    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.

    Three Year Limited-Warranty
    As an industry-leading hard drive manufacturer, WD stands behind their surveillance storage solutions with a 3-year limited warranty included with every WD Purple™ drive.
