20TB of Enterprise-Class Storage Built for 24/7 Servers

The WD Gold 20TB is a 3.5-inch enterprise hard drive designed for servers, storage arrays and business NAS systems running around the clock. It spins at 7200 RPM with a 512MB cache and reaches sustained transfer rates of up to 269 MB/s. It uses CMR recording, and OptiNAND technology pairs the platters with integrated flash for higher capacity and better performance.
