The Western Digital Ultrastar DC HC570 22TB hard drive is engineered to meet the growing demands of modern data centers, including AI/ML, 5G networks, and IoT applications. By leveraging a 10-disk CMR platform, this drive delivers exceptional data density, allowing data centers to expand their storage capacity without increasing their physical footprint or power consumption.

Featuring second-generation OptiNAND technology, the DC HC570 combines traditional spinning media with an iNAND Universal Flash Storage drive. This integration improves drive resiliency during emergency power-off events and introduces ArmorCache, a feature that provides the performance benefits of write-cache-enabled mode alongside the data protection of write-cache-disabled mode.

Built for enterprise-grade reliability, the Ultrastar DC HC570 is designed to handle heavy application workloads of up to 550TB per year. With a projected 2.5 million hours MTBF and a 5-year limited warranty, it provides the quality and security required for mission-critical data storage at scale.
