About the WD Ultrastar HC560 20 TB 3.5 Inch SATA 6Gb/s Enterprise HDD

Built for hyperscale cloud storage and petabyte-scale data lakes across the GCC and Asia-Pacific regions, the WD Ultrastar HC560 20TB (Part Number WUH722020ALE6L4) combines helium-sealed density with proven enterprise reliability. Western Digital's ePMR technology and OptiNAND delivers 20TB per drive while maintaining a 7200 RPM operational profile, enabling operators to reduce spindle count, power consumption, and total cost of ownership in large-capacity storage clusters.

The HC560 20TB is engineered for warm and cold archival workloads where sequential throughput and operational consistency matter more than random I/O. With sustained sequential read speeds up to 291 MB/s, a 512 MB cache, and 2.5 million TBW endurance rating, this drive handles continuous ingest from AI training pipelines, government compliance archives, and multi-tenant cloud object storage without degradation. A single 24-bay enclosure yields over 480TB raw capacity—ideal for organisations prioritising on-premises data sovereignty and avoiding recurring cloud egress fees.

  • Capacity & Density: 20TB 3.5" form factor per drive; 480TB+ per standard 24-bay node
  • Performance: 291 MB/s sustained read; 7200 RPM; 512 MB cache for smooth large-file operations
  • Reliability: 2.5 million TBW endurance; helium-sealed design; OptiNAND reduces thermal variance
  • Use Cases: Cloud archival, data lake backfills, hyperscale object storage, AI training dataset repositories
