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. With WD Purple, you get reliable, surveillance-class storage that’s tested for compatibility in a wide range of security systems, and some of our latest models (WD22PURZ, WD42PURZ, and WD63PURZ) have improved power efficiency. Exclusive All Frame™ technology helps reduce frame loss and improve overall video playback.
Western Digital’s Exclusive All Frame Technology
All WD Purple drives are equipped with All Frame 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/year1 – up to three times that of desktop drives – to handle the unique demands of mainstream video surveillance DVR and NVR systems.
