Western Digital® Purple™ NV 3.5-inch, high-capacity 4 TB and 6 TB hard drives for scalable NVR and VMS surveillance systems.

The WD Purple NV range suits applications with increased storage capacity and higher hard drive bay counts; greater numbers of attached cameras; where exceptional reliability and durability are essential. WD Purple NV drives withstand ‘always-on’ digital surveillance recording environments yet offer low power consumption and many advanced performance 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*.

* The specific number of cameras that can be supported will be dependent on a number of criteria; types and capability of cameras installed (resolution, fps, additional features) and the system’s hardware and software capability.
