WD Purple Pro 3.5" 24TB, 7200 RPM, 512MB, 550 WRL, SATA III Hard Drive, for Surveillance

The WD Purple Pro is a 24 TB internal hard drive engineered for high-demand surveillance systems. It is specifically built for advanced AI-enabled recorders, video analytics servers, and deep learning solutions that require substantial storage capacity and consistent performance. A 7200 RPM spindle speed and a large 512 MB cache facilitate the handling of high-resolution video streams and continuous data recording from multiple sources. The drive's firmware is optimized for write-intensive, low bit-rate, high stream-count applications typical of professional surveillance setups.

This drive is constructed for sustained, 24/7 operation, a critical requirement for security and monitoring applications. Its reliability is indicated by a 2.5 million-hour Mean Time Between Failures (MTBF) and a workload rating of 550 TB per year. These specifications demonstrate its capacity to manage the intensive write cycles of modern surveillance recording without performance degradation. The drive also incorporates S.M.A.R.T. technology, which allows for proactive monitoring of drive health to help maintain system integrity and data availability.
