Western Digital® scales up surveillance-class HDD line

Western Digital® has introduced the WD Purple™ NV range of 3.5-inch, high-capacity, 4 TB and 6 TB hard drives designed to meet the demands of 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; and where exceptional reliability and durability is essential. The WD Purple NV range withstands the demands of ‘always-on’ digital surveillance applications, yet offer low power consumption and many advanced performance features. When used for high-camera-count digital surveillance systems, the NV range improves high-definition video playback.


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.
