WD Purple Pro 3.5" 12TB, 7200 RPM, 256MB, SATA III Hard Drive for Surveillance

The Western Digital WD Purple Pro is a 12 TB internal hard drive engineered for AI-enabled surveillance recorders, video analytics appliances, and deep-learning servers. It utilizes a standard 3.5-inch form factor and a SATA 6 Gb/s interface for broad system compatibility. The drive features AllFrame AI technology, which is designed to support the recording of up to 64 single-stream HD cameras while simultaneously managing up to 32 AI streams. This technology helps to minimize frame loss and improve data flow management in high-demand video surveillance workloads.

This model operates at a 7200 RPM spindle speed with a 256 MB cache to facilitate responsive data access and write performance. Built for reliability in continuous 24/7 environments, it has a workload rating of up to 550 TB per year and a Mean Time Between Failures (MTBF) of 2.5 million hours. The inclusion of Rotational Vibration (RV) sensors allows the drive to maintain consistent performance in multi-bay enclosures by detecting and compensating for vibrations. S.M.A.R.T. support is also included for proactive drive health monitoring.
