Western Digital has introduced WD Purple NV, a purpose-built line of 3.5″, high-capacity 4 and 6 TB hard drives for the greater demands of scalable network video recorder (NVR) surveillance systems.
Compared with standard WD Purple drives, Purple NV is designed for larger-scale network surveillance systems utilising higher hard drive bay counts and greater numbers of attached cameras, which demand increased storage capacity and durability. The new drives’ high capacities also enable long video retention periods for analysis and reference. WD Purple NV is also designed to withstand the demands of always-on digital NVR recording environments. It offers low power consumption and many advanced performance features typically reserved for higher end surveillance storage.
