Western Digital PURPLE 3.5” DVR HDD 1TB 64MB WD11PURZ

​WD Purple™ drives are designed to meet the challenges of 24×7 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 alwayson 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 WD 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
• Supports up to 180TB/yr workload rate and up to 16 bays
