WD Red Pro 3.5" 12TB, 7200 RPM, 512MB, 550 WRL, SATA III Hard Drive for NAS

This Western Digital Red Pro hard drive is engineered for high-intensity workloads within multi-bay commercial and enterprise NAS environments. It is built for continuous 24/7 operation, providing a reliable storage solution for storing, sharing, and collaborating on large data sets. The drive's construction supports a workload rate of up to 550 TB per year and has a mean time between failures of 1.2 million hours, ensuring long-term dependability in demanding RAID-optimized systems. This makes it suitable for intensive data archival and access scenarios.

The drive's performance is facilitated by a 7200 RPM spindle speed and a large 512 MB cache, which work together to reduce latency and accelerate data processing. It connects via a SATA III interface, supporting transfer rates up to 6 Gbit/s and delivering sustained read and write speeds of 267 MB/s. Equipped with rotational vibration sensors, the drive can detect and counteract vibrations typically found in multi-drive enclosures. This technology helps maintain stable performance and data integrity when used alongside other drives.
