Hard Drive, 2TB, Designed Specifically for Surveillance Use
Uncompromising Storage with a Surveillance Hard Drive
These drives are engineered specifically for surveillance to help withstand the elevated heat fluctuations and equipment vibrations within NVR environments. An average desktop drive is built to run for only short intervals, not the harsh 24/7 always-on environment of a high-definition surveillance system. With our hard drives, you get reliable, surveillance-class storage that’s tested for compatibility in a wide range of security systems. Exclusive AllFrame™ technology helps reduce frame loss and improve overall video playback.
Exclusive AllFrame Technology
All drives are equipped with AllFrame technology, which improves ATA streaming to help reduce frame loss and improve overall video playback, within a multitude of security video solutions.
Enhanced Workload Ratings
These drives feature a workload rating of up to 180TB/year2 - up to three times that of desktop drives - to handle the unique demands of mainstream video surveillance DVR and NVR systems.
Multiple Cameras, Multiple Streams
Modern recorders now support multiple video streams per camera. WD Purple drives support up to 64 single-stream HD cameras (6TB1 and above), and can also support many of the latest cameras that transmit multiple streams to enable basic AI functionality. With so many options, you have the flexibility to upgrade or expand your security applications in the future.
Designed for Today's and Tomorrow's Surveillance Solutions
With an MTBF of up to 1 million hours3, WD Purple drives are engineered for mainstream surveillance DVRs and NVRs that operate 24/7. With tarnish-resistant components3 and support for more than eight bays4, WD Purple drives deliver reliable operation even in harsh environments.
