WD Purple Pro 3.5" 12TB, 7200 RPM, 512MB, SATA III Hard Drive for Surveillance

The WD Purple Pro is a 3.5-inch internal hard drive engineered for advanced, AI-driven surveillance systems. It is optimized for video analytics servers and deep learning solutions that require high-capacity, reliable storage for continuous data recording. The drive's architecture is built to manage high-temperature, always-on environments, making it suitable for complex security deployments. Its firmware is tuned to handle the high-stream-count, write-intensive workloads characteristic of modern video surveillance.

To ensure data integrity and performance in multi-drive systems, this model incorporates several key technologies. Integrated rotational vibration (RV) sensors help mitigate the effects of ambient vibration, which is common in multi-bay server chassis, thereby maintaining consistent read/write performance. The drive is also rated for a high workload and a substantial Mean Time Between Failures (MTBF), reflecting its durability for enterprise-grade surveillance applications that operate around the clock.
