WD Gold 3.5" 12TB, 7200 RPM, 512MB, SATA III Hard Drive, Enterprise

This internal hard disk drive is an Enterprise Class component designed for sustained, high-volume workloads in data centers and server environments. It features a substantial 12 TB storage capacity and adheres to the standard 3.5-inch form factor. Reliability is a core feature, indicated by the 2.5 million hour Mean Time Between Failures (MTBF) rating and a workload rate limit of 550 TB per year. The drive is built for 24/7 continuous operation, making it suitable for high-availability systems.

Utilizing a SATA interface with a 6 Gbit/s transfer rate, this HDD maintains a spindle speed of 7200 RPM. Sequential read and write speeds are rated at 267 MB/s, supported by a large 512 MB cache buffer, with an average latency measured at 9 ms. Performance stability during heavy use is enhanced by integrated Rotational Vibration (RV) sensors, which compensate for external system movements. The drive supports S.M.A.R.T. diagnostics and includes end-to-end data protection mechanisms to maintain data integrity across the platform.
