WD Purple™ 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 WD Purple, 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.

 

  • Engineered specifically for mainstream surveillance systems
  • AllFrame technology delivers optimizations for write-intensive, low bit-rate, high stream-count workloads typical to mainstream surveillance applications
  • Tarnish-resistant components
  • 3-year limited warranty
 
 
 
 
Western Digital’s Exclusive AllFrameTM Technology
 
All WD Purple™ 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.
 
 
 
 
 
 
Multiple Cameras, Multiple Streams
 
Modern recorders now support multiple video streams per camera. Select WD Purple™ drives support up to 64 single-stream HD cameras (see specifications table), 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 hours, WD Purple™ drives are engineered for mainstream surveillance DVRs and NVRs that operate 24/7. With tarnish resistant components and support for more than eight bays², WD Purple drives deliver reliable operation in surveillance systems even in harsh environments.
 
 
 
 
 
Wide Compatibility. Seamless Integration.
 
WD Purple™ hard drives are built with compatibility in mind, so you can quickly and seamlessly add capacity to your surveillance system. With a wide range of industryleading enclosures and chipsets supported, you’re sure to find the DVR or NVR configuration that’s right for you.
 
 
 
 
 
 
Proactive Storage Management with WDDA
 
Western Digital Device Analytics™ (WDDA) provides a wealth of storage device parametric operational and diagnostic data to the system; algorithms interpret the data and direct the system to alert system administrators of specific recommended actions to address potential issues. WDDA is intended to empower OEMs, system integrators, and IT professionals to better monitor and proactively manage supported storage devices to maintain optimal operation.
 
 
 
 
 
Three-Year Limited Warranty

As an industry-leading hard drive manufacturer, Western Digital stands behind their surveillance storage solutions with a 3-year limited warranty included with every WD Purple™ drive
