1. Designed with tarnish-resistant components for harsh environments, and with additional robustness for multi-bay enclosures.
Western Digital is a worldwide leader in the hard drive industry. With WD Purple™ Pro smart video storage, you have a drive engineered for high performance, durability and workload capability for advanced always-on AI-enabled smart video recorders, appliances, and servers. Efficiently and effectively extract value and insights from streamed and stored video, and help deliver a smarter world with advanced WD Purple Pro smart video storage.
Modern recorders now support multiple video streams per camera. WD Purple™ Pro drives are optimized to support up to 64 HD single-stream cameras2
2 Single stream per camera @ 3.2Mbps (1080p, H.265, 25 fps). Results may vary depending on camera resolution, file format, frames per second, software, system settings, video quality, and other factors
3 Projected values. When final, MTBF and AFR specifications will be based on a sample population and are estimated by statistical measurements and acceleration algorithms under typical operating conditions, workload of 220TB/year and drive temperature of 40°C. Derating of MTBF and AFR will occur above these parameters, up to 550TB writes per year and 65°C drive temperature. MTBF and AFR ratings do not predict an individual drive’s reliability and do not constitute a warranty.

Western Digital Device Analytics
Security is paramount in today’s 24x7 world and robust surveillance helps provide that security and peace of mind. Unfortunately, continuous surveillance recording can be interrupted by unexpected events, including power outage/disruption, surveillance equipment failure, network infrastructure disruption, and even storage device failure.
While rare, storage failure can occur, resulting in a reduction in the total recording duration and the failover recording may be compromised.If repair or replacement of the storage device is required, it may result in recording downtime, a short-term security vulnerability, and unexpected expenses incurred because of special support or services.
The new Western Digital® Device Analytics™ (WDDA) provides for the proactive monitoring of the storage subsystem to preempt unexpected disruptions. When implemented in a surveillance solution, it analyzes the operational parameters and the data from the embedded device sensors. This persistent monitoring enables the detection of problematic operating conditions and reports such conditions to the system administrators; it also suggests predefined actions that can be taken to maintain optimal operation of the storage devices.
Proper use of WDDA to proactively manage storage in a surveillance system can result in key benefits, including:
- Potentially fewer field service calls – Empower customers and integrators to proactively monitor the storage subsystem, and if needed, perform corrective actions on their own, thereby resulting in reduced TCO.
- Makes more data analytics available to help troubleshoot and proactively reduce a greater number of potential issues, thereby gaining insights for better system design. Adds a valuable tool for the integrator/installer to actively monitor system status and prevent potential problems to keep their customers happy by increasing system availability time.
- Allows for data backup and avoidance of customer data loss, downtime, and a bad end-user experience by helping to identify potential HDD candidates for replacement prior to failure, thereby increasing customer satisfaction.
