The WD Ultrastar DC HC570 22TB Enterprise HDD (0F48155) is a high-performance, data center-class storage solution designed for organizations that require massive capacity, reliability, and continuous uptime. Built for modern workloads such as cloud storage, enterprise backup, AI data lakes, and large-scale virtualization environments, this drive delivers the durability and efficiency expected from Western Digital’s Ultrastar lineup.

At its core, the HC570 leverages helium-sealed technology to reduce internal friction and power consumption while enabling higher areal density across its multi-disk architecture. Combined with OptiNAND technology, it improves metadata handling and enhances overall drive efficiency, making it suitable for sustained, high-volume workloads.

With 22TB of storage, businesses can significantly reduce rack space usage while increasing storage density per system. The drive operates at 7200 RPM and delivers sequential transfer speeds of up to 291 MB/s, ensuring consistent throughput for large file transfers and enterprise workloads.

Engineered for 24/7 reliability, the Ultrastar HC570 is rated for high endurance with an MTBF of up to 2.5 million hours, making it ideal for mission-critical environments where downtime is not an option. Its CMR (Conventional Magnetic Recording) design ensures stable write performance even under heavy workloads, unlike SMR-based alternatives.

Whether deployed in hyperscale data centers or enterprise storage arrays, the WD Ultrastar DC HC570 offers a balance of capacity, performance, and long-term reliability that meets modern data infrastructure demands.
