WD, a Western Digital company and storage industry leader, today introduced WD Purple NV, a purpose-built line of 3.5-inch, high-capacity 4 TB and 6 TB hard drives for the greater demands of scalable network video recorder (NVR) surveillance systems.

Compared with standard WD Purple drives, the new member of the WD's surveillance video recording family of drives, WD Purple NV, is designed for larger-scale network surveillance systems utilizing 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."The global video surveillance market is expanding with the increased accessibility to easy-to-use systems for small businesses and municipalities," said Matt Rutledge, senior vice president of HDD marketing at WD. "WD optimized the WD Purple NV line of hard drives 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 hard drives a perfect solution for NVR systems needing high quality recording and playback and high capacity storage."

Features
WD Purple NV hard drives are equipped with an 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. WD Purple includes exclusive firmware upgrades that protect against video pixilation and interruptions within a surveillance system.
• Premium Protection - Designed with tarnish-resistant components, WD Purple NV offers premium protection in harsh environments where surveillance systems can be installed.
• Support for High-Camera-Count Systems - WD Purple NV hard drives are optimized to support systems utilizing high numbers of high-definition surveillance cameras, giving you the flexibility to upgrade and expand your security system in the future. Higher storage capacities also allow you to store the surveillance footage for a longer period of time, especially in situations when every second counts.

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