SURVEILLANCE HARD DRIVES
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 8TB and higher drives have additional performance
headroom to support a new generation of AI-enabled NVRs, video analytics appliances,
and deep-learning servers.
Industry-leading storage. Surveillance you can trust.
Western Digital is a worldwide leader in the hard drive industr y. 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, improve overall video playback, and increase
the number of hard drive bays supported within an NVR. WD Purple capacities up to
6TB feature AllFrame 4K technology enabling high-quality recording in a multitude of
security systems. WD Purple 8TB, 10TB, 12TB, 14TB, and 18TB capacities feature AllFrame
AI technology that enables not only recording multiple streams per camera but also
supports an additional 32 streams for Deep Learning analytics within the system.
Enhanced Workload Ratings
WD Purple drives with AllFrame 4k technology feature a workload rating of up to 180TB/
year – up to three times that of desktop drives – to handle the unique demands of
modern video sur veillance DVR and NVR systems. WD Purple drives with AllFrame AI
technology feature a workload rating up to 360TB/year to support the growing use of
deep learning analytics.
Multiple Cameras, Multiple Streams
Modern recorders now support multiple video streams per camera. WD Purple™ 8TB
and higher capacity drives are optimized to support up to 64 HD single-stream cameras13,
and can also support the latest smart cameras that transmit multiple streams. With so
many options, you have the flexibility to upgrade or expand your security system in the
future.
