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 alwayson environment of a high-definition surveillance system. With WD Purple, 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. WD Purple 8TB⁴ and higher drives have additional performance
headroom to support a new generation of AI-enabled NVRs, video analytics appliances,
and deep-learning servers.
