Western Digital WD64PURZ | WD PURPLE Surveillance HDD 3.5" 6TB, 256MB

WD Purple drives are specifically designed for surveillance to help withstand the elevated heat fluctuations and equipment vibrations in NVR environments. A typical desktop drive is built to run during short intervals, not the harsh 24/7 always-on environment in a high-definition surveillance system.

With WD Purple, you get reliable surveillance-class storage that has been tested for compatibility in a wide range of security systems, and some of the latest models (WD22PURZ, WD42PURZ, and WD64PURZ) have improved energy efficiency. Exclusive AllFrame technology™ helps reduce image loss and improve overall video playback.
