Western Digital Ultrastar DC HC560 20TB 7200RPM SATA 6Gb/s 3.5-inch Helium ISE Enterprise HDD

The Western Digital Ultrastar DC HC560 is a 20TB, 3.5-inch enterprise hard disk drive built on HelioSeal helium-sealed platform technology, spinning at 7200 RPM with a SATA 6Gb/s interface. The helium-filled enclosure reduces internal turbulence and drag on the disk platters, enabling Western Digital to stack nine platters within a standard 3.5-inch form factor while maintaining lower operating power consumption compared to air-filled drives of equivalent capacity. The drive ships with Instant Secure Erase (ISE) functionality, allowing rapid cryptographic sanitization of stored data to meet enterprise data-at-rest security and decommissioning requirements without physical destruction.

The HC560 is rated for a workload of up to 550TB per year and carries a mean time between failures (MTBF) rating of 2,500,000 hours, reflecting the reliability standards expected in always-on datacenter environments. The drive supports rotational vibration (RV) sensors to compensate for vibration in high-density multi-drive enclosures such as JBODs, storage servers, and rack-mounted NAS arrays. A 512MB data buffer supports sustained throughput for sequential and mixed read/write workloads typical of large-scale storage deployments.

Designed for cloud infrastructure, hyperscale storage, and enterprise AI data pipelines, the Ultrastar DC HC560 is suitable for environments demanding high raw capacity per drive bay, low idle power draw, and predictable long-term reliability. Its compatibility with standard SATA backplanes ensures broad integration across server platforms, storage enclosures, and scale-out object storage systems commonly deployed across datacenter and edge infrastructure in global enterprise environments.

Ideal for

• Hyperscale and cloud object storage systems requiring maximum raw capacity per drive bay to reduce rack-space and power overhead
• AI and machine learning data lake storage, providing high-capacity sequential read throughput for training dataset ingestion and model checkpointing
• Enterprise backup and archive repositories where high-density SATA drives reduce total infrastructure footprint for long-retention data tiers
• High-density NAS and JBOD enclosures in media and entertainment workflows requiring large unstructured data storage for video asset management
• On-premises surveillance and security video storage platforms demanding continuous write endurance across sustained 24/7 recording workloads
• Compliance and regulatory cold-to-warm storage tiers where ISE capability enables rapid, auditable drive sanitization at end-of-life or redeployment
