Proactive Storage Management With WDDA 

Western Digital® Device Analytics™ (WDDA) provides a wealth of storage device parametric operational and diagnostic data to compatible systems; 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. Learn More


1 Workload Rate is defined as the amount of user data transferred to or from the hard drive. Workload Rate is annualized (TB transferred ✕ (8760 / recorded power-on hours)). Workload Rate will vary depending on your hardware and software components and configurations
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.
As used for storage capacity, 1TB < one trillion bytes. Actual user capacity may be less, depending on operating environment. 0

Western Digital Device Analytics

(WDDA), is a new device analytics capability supported by Western Digital’s line of surveillance-optimized storage products. WDDA enables administrators to proactively manage storage and to maintain optimal performance to preempt unexpected failures.


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.
With Western Digital surveillance-optimized storage, surveillance is more than just seeing: It is looking ahead. Capture, store, and analyze data with edge-to-core solutions that adapt to new innovations.
