WD Purple Pro 3.5" 22TB, 7200 RPM, 512MB, 550 WRL, SATA III Hard Drive for Surveillance

The WD Purple Pro is a 22 TB internal hard drive engineered for high-demand video surveillance and analytics applications. It operates on a SATA 6 Gbit/s interface and features a spindle speed of 7200 RPM to facilitate consistent data recording and retrieval from multiple sources. This drive is specifically designed for continuous 24/7 operation within AI-enabled recorders, video analytics servers, and deep learning systems. Its integrated AllFrame AI technology is optimized to support data streams from up to 64 high-definition cameras simultaneously, managing the intensive write workloads of smart video applications.

This model's architecture is focused on reliability and performance within multi-drive environments. It is equipped with a large 512 MB cache to streamline data flow and improve response times during complex read/write operations. Built-in rotational vibration (RV) sensors detect and counteract disturbances, ensuring stable performance when installed in large-scale server or NAS chassis. The drive is rated for a workload of 550 TB per year and has a Mean Time Between Failures (MTBF) of 2.5 million hours, reflecting its construction for continuous, enterprise-grade data handling.
