# WD PURPLE 16TB 3.5 SAT

The **Western Digital Purple Pro 16TB (WD161PURP/WD161PURZ)** is a specialized, enterprise-class hard drive engineered specifically for the extreme demands of 24/7, always-on smart video surveillance systems and AI-enabled analytics servers.

Unlike standard desktop drives that are built to run for a few hours a day, the Purple Pro series is designed to handle continuous heavy write workloads while resisting the heat and vibration typically found in multi-bay NVRs (Network Video Recorders).

## Key Features

-   **Exclusive AllFrame™ AI Technology:** This firmware reduces frame loss and improves overall video playback. It supports up to 32 AI streams for deep learning analytics within the system, ensuring smooth, uninterrupted footage capture.
    
-   **Massive Camera Support:** Optimized to support up to 64 single-stream HD cameras simultaneously, making it ideal for large-scale security deployments.
    
-   **Enterprise-Class Workload Rating:** Built to handle up to **550TB per year** — up to three times the workload rating of standard WD Purple drives and drastically higher than regular desktop drives.
    
-   **High Durability & Reliability:** Features a Mean Time Between Failures (MTBF) of up to 2.5 million hours. It also includes tarnish-resistant components to protect the drive in harsh, high-heat environments.
    
-   **Active Hovering Technology:** Protects the drive against vibrations caused by surrounding drives in large, multi-bay storage enclosures.
