WD, a Western Digital (WDC) company, introduced Purple NV, a purpose-built line of 3.5-inch, high-capacity 4 and 6TB HDDs for the demands of scalable network video recorder (NVR) surveillance systems.


Compared with standard Purple drives, the new member of the surveillance video recording family of drives,Purple NV is designed for larger-scale network surveillance systems utilizing higher HDD bay counts and greater numbers of attached cameras, which demand increased storage capacity and durability. The new drives' high capacities enable long video retention periods for analysis and reference. Purple NV is 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.

"The global video surveillance market is expanding with the increased accessibility to easy-to-use systems for small businesses and municipalities," said Matt Rutledge, SVP, HDD marketing, WD. "WD optimized the WD Purple NV line of HDDs for NVR digital surveillance systems to improve high-definition video playback for high-camera-count applications. NVR surveillance systems can produce incredible amounts of data which makes the WD Purple NV HDDs a perfect solution for NVR systems needing high quality recording and playback and high capacity storage."


Purple NV HDDs are equipped with array of exclusive WD technologies, including:

  • AllFrame - When combined with ATA streaming support, AllFrame technology helps to reduce video footage loss with a proprietary cache policy management technology to help improve data flow and playback. Purple includes exclusive firmware upgrades that protect against video pixilation and interruptions within a surveillance system.

  • Premium protection - Designed with tarnish-resistant components, Purple NV offers premium protection in harsh environments where surveillance systems can be installed.

  • Support for high-camera-count systems - Purple NV HDDs are optimized to support systems utilizing high numbers of HD surveillance cameras, giving the flexibility to upgrade and expand security systeme. Higher storage capacities also allow to store the surveillance footage for a longer period of time, especially in situations when every second counts [1].

Purple NV 6TB surveillance HDDs are shipping to customers for qualification and are covered by a three-year limited warranty. WD Purple NV 4TB HDDs will be available for qualification later this quarter. Both the 6TB and 4TB capacities will be shipping in volume within the quarter.
