WD Purple 2TB SATA 6Gb/s CE HDD 3.5inch internal 256MB Cache 24x7 Bulk

WD Purple drives are designed to meet the challenges of 24 x 7 video surveillance recording. These 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 drives, 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.

• Engineered for mainstream surveillance systems
• WD AllFrame technology delivers optimizations for write-intensive, low bit-rate, high stream-count workloads typical to mainstream surveillance applications
