WD Ultrastar DC HC560 3.5" 20TB, 7200 RPM, 512MB, SATA III Hard Drive, Enterprise

The Western Digital Ultrastar DC HC560 is a high-capacity internal hard drive engineered for enterprise-level data storage in servers and workstations. It utilizes HelioSeal technology, which seals the drive with helium to reduce internal turbulence, enabling a 20 TB capacity within a standard 3.5-inch form factor. This design contributes to operational efficiency and reliability in data center environments. The drive also integrates OptiNAND technology to improve performance and data protection during unexpected power loss events, enhancing overall system resilience.

Performance is delivered through a 7200 RPM spindle speed and a SATA 6 Gb/s interface, facilitating consistent data throughput for demanding 24/7 workloads. Integrated rotational vibration (RV) sensors detect and counteract disturbances, ensuring stable operation in dense, multi-drive enclosures. This model is specified for a workload rate of 550 TB per year and includes S.M.A.R.T. monitoring capabilities for drive health analytics. These features support proactive system maintenance in critical server and storage applications.
