WD Purple 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.

Industry-Leading Storage. Surveillance You Can Trust.
Western Digital 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.

Western Digital's Exclusive AllFrame Technology
All WD Purple drives are equipped with AllFrame technology, which improves ATA streaming to help reduce frame loss and improve overall video playback, within a multitude of security video solutions.

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 and can also support many of the latest cameras that transmit multiple streams to enable basic AI functionality. With so many options, you have the flexibility to upgrade or expand your security applications in the future.

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.

Proactive Storage Management with WDDA
Western Digital Device Analytics (WDDA) provides a wealth of storage device parametric operational and diagnostic data to the system; algorithms interpret the data and direct the system to alert system administrators of specific recommended actions to address potential issues. WDDA is intended to empower OEMs, system integrators, and IT professionals to better monitor and proactively manage supported storage devices to maintain optimal operation.
