WD Ultrastar DC HC560 20TB 3.5-inch SAS 12Gb/s 7200 RPM Enterprise Nearline HDD

The WD Ultrastar DC HC560 is a 20TB 3.5-inch enterprise nearline hard drive built on Western Digital's ninth-generation HelioSeal platform, utilizing helium-sealed enclosure technology to reduce internal turbulence and enable higher areal density across nine magnetic platters. The drive connects via SAS 12Gb/s interface, delivering sustained transfer rates suited to high-throughput storage infrastructures, while spinning at 7200 RPM to balance sequential performance with energy efficiency. A 512MB cache buffer supports burst workloads, and the drive is rated for up to 2.5 million hours MTBF, reflecting its engineering for continuous operation in demanding datacenter environments.

The HC560 is engineered with Advanced Format (512e/4Kn) sector technology and supports rotational vibration (RV) compensation, making it suitable for high-density multi-drive enclosures where vibration from adjacent drives can degrade performance. The drive carries a 550TB per year workload rating, positioning it as a nearline storage device designed for large-scale sequential and mixed workloads rather than transactional IOPS-heavy applications. PowerChoice and PowerControl technologies provide granular power state management, enabling operators to reduce energy consumption during idle periods at scale.

With its combination of 20TB raw capacity, enterprise-grade SAS connectivity, and helium-sealed mechanical design, the Ultrastar DC HC560 addresses the storage density requirements of modern hyperscale deployments, object storage systems, AI training dataset repositories, and large-scale backup and archival infrastructures. The drive is compatible with leading storage platforms and qualifies under Western Digital's rigorous enterprise validation program, making it a reliable building block for petabyte-scale storage architectures across datacenter, cloud, and AI/ML environments served globally including UAE, GCC, EMEA, and APAC regions.

Ideal for

• Hyperscale and cloud datacenter object storage deployments requiring maximum capacity per rack unit
• AI and machine learning training dataset storage, providing high-capacity sequential read throughput for large model ingestion pipelines
• Large-scale backup and disaster recovery repositories where high per-drive capacity reduces hardware footprint and power consumption
• High-density NAS and SAN storage arrays for enterprise content repositories, media archives, and genomics data lakes
• Surveillance and video analytics platforms requiring continuous write workloads across large multi-drive enclosures
• Cold and warm tier storage in tiered storage architectures, absorbing capacity overflow from higher-performance NVMe or SAS SSD tiers
