Surveillance storage you can trust.
WD Purple AI is purpose-built for security systems, giving you stable recording, smooth playback, and headroom for AI analytics when you need to review critical footage.
Engineered for 24/7 Surveillance
WD Purple drives are engineered specifically for surveillance to help withstand the elevated heat fluctuations and equipment vibrations inside NVR and DVR chassis. Average desktop drives are not designed for the harsh, always-on duty cycle of a high-definition surveillance system. WD Purple AI drives deliver the reliability, performance, and endurance that security systems demand.
Western Digital AllFrame AI Technology
All WD Purple AI drives feature AllFrame AI technology, which improves ATA streaming to help reduce frame loss, minimise pixellation, and enhance overall video playback. In addition to recording multiple video streams per camera, AllFrame AI enables additional AI streams for deep-learning analytics on compatible recorders and analytics appliances.
Enhanced Workload Rating
WD Purple AI drives provide an increased workload rating of up to 360 TB/year, up to three times that of many desktop drives, to support continuous multi-stream recording and AI processing in modern video surveillance systems. This makes them ideal for NVRs that handle both video storage and on-box analytics.
Multiple Cameras, Multiple Streams
Modern recorders often support multiple video streams per camera (for live view, recording, smart analytics and mobile access). WD Purple AI drives are optimised to support up to 64 single-stream HD cameras (and smart cameras with multiple streams), giving you the freedom to expand or upgrade your surveillance system without compromising on storage performance.
Designed for Today’s and Tomorrow’s Solutions
With an MTBF rating of up to 1.5 million hours (model dependent) and support for multi-bay systems, WD Purple AI drives help deliver reliable long-term operation in larger surveillance deployments. Tarnish-resistant components and surveillance-class firmware further enhance longevity in demanding environments.
Proactive Storage Management with WDDA
Western Digital Device Analytics (WDDA) provides rich parametric and diagnostic data to compatible systems. Analytics algorithms can interpret this data and surface clear recommendations, helping installers and IT admins proactively manage drive health and maintain optimal system reliability over time.
