WD Gold 3.5" 20TB, 7200 RPM, 512MB, 550 WRL, SATA III Hard Drive, Enterprise

The Western Digital WD Gold 20TB hard drive is an enterprise-class storage solution engineered for servers and high-performance workstations. It features a 3.5-inch form factor and connects via a SATA 6Gb/s interface for broad system compatibility. The drive operates at a spindle speed of 7200 RPM, providing consistent data access for demanding applications. Its 20 TB capacity is suitable for large-scale data archiving, cloud storage, and other environments requiring substantial storage density within a standard server chassis.

This model is built for continuous 24/7 operation and is rated for a workload of up to 550 TB per year. Performance is supported by a 512 MB buffer, which facilitates sustained data transfer rates of up to 291 MB/s. To ensure data integrity and stable operation in multi-drive environments, the drive incorporates rotational vibration (RV) sensors to counteract vibration effects. The unit has a mean time between failures (MTBF) rating of 2.5 million hours, indicating a design focus on long-term reliability in enterprise settings.
