WD Red Pro 3.5" 26TB, 7200 RPM, 512MB, 550 WRL, SATA III Hard Drive, for NAS

The WD Red Pro is a 3.5-inch internal hard drive engineered for high-intensity workloads in multi-bay network-attached storage (NAS) systems. Its design prioritizes reliability for continuous, 24/7 operation in commercial and enterprise environments. The drive incorporates rotational vibration (RV) sensors to maintain consistent performance and data integrity when used in multi-drive enclosures. This makes it suitable for managing large volumes of data in demanding, collaborative applications.

Performance is delivered through a 7200 RPM spindle speed and a 512 MB cache, which facilitate faster data access and help reduce latency. The drive achieves sequential read and write speeds of up to 272 MB/s, supporting efficient file transfers and data streaming. It is rated for a workload of up to 550 TB per year and features a Mean Time Between Failures (MTBF) of 2.5 million hours. These specifications are aligned with the requirements for data-intensive storage tasks in professional settings.
