WD®,  a Western Digital (NASDAQ: WDC) 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 counts¹.
