WD Gold 3.5" 22TB, 7200 RPM, 512MB, 550 WRL, SATA III Hard Drive, Enterprise

This WD Gold internal hard disk drive is specifically engineered for high-capacity enterprise and data center applications. It offers a substantial storage capacity of 22 TB within the standard 3.5-inch form factor, utilizing a SATA 6 Gbit/s interface for host connectivity. The drive is certified for continuous, 24/7 operation in professional environments that demand sustained throughput. Reliability metrics include a Mean Time Between Failures (MTBF) rating of 2.5 million hours.

Performance is maintained by a spindle speed of 7200 RPM, complemented by a large 512 MB cache buffer. Sequential operations provide a maximum sustained read speed of 291 MB/s, with an average latency measured at 4.16 ms. Designed to handle intense use, the drive specifies an annual workload limit of 550 TB per year. Advanced operational features include S.M.A.R.T. status monitoring and integrated Rotational Vibration (RV) sensors, supporting stable function within multi-drive chassis and high-density storage arrays.
