WD Purple 1TB surveillance hard drive (WD11PURZ)

WD Purple 1TB overview

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. Exclusive AllFrame technology helps reduce frame loss and improve overall video playback.

The WD11PURZ combines 1TB of capacity, 64MB cache, transfer rates up to 180MB/s, a workload rating of 180TB/year and 1,000,000 hours MTBF (projected).

Western Digital technologies on this drive: AllFrame.

Every WD Purple 1TB sold by ARC IP Networks is genuine, new Western Digital stock with the full 3-year limited manufacturer's warranty, delivered Australia-wide at competitive prices. Australian stock from ARC IP Networks.
