Western Digital Ultrastar DC HC560 20TB 7200RPM SAS 12Gb/s 3.5-inch Helium ISE Enterprise HDD

The Western Digital Ultrastar DC HC560 is a 20TB 3.5-inch enterprise hard disk drive engineered for high-density datacenter deployments demanding sustained throughput and exceptional reliability. Built on HelioSeal technology, the drive is hermetically sealed with helium to reduce internal turbulence and friction, enabling a higher platter count within the standard 3.5-inch form factor while simultaneously lowering power consumption and operating temperatures compared to air-filled alternatives. The SAS 12Gb/s interface delivers dual-port connectivity inherent to the SAS protocol, providing redundant path access critical for mission-critical storage infrastructures.

The HC560 operates at 7,200 RPM and is rated for a workload of 550TB per year, reflecting its positioning as a drive intended for always-on enterprise environments including cloud-scale object storage, bulk data repositories, and AI/ML training dataset storage. The drive carries an annualized failure rate (AFR) of 0.35% and a mean time between failures (MTBF) rating of 2.5 million hours, underscoring the reliability engineering required for large-scale storage arrays. Instant Secure Erase (ISE) functionality is incorporated via the part number suffix, enabling rapid and cryptographically verifiable data sanitization at end-of-life or drive redeployment without the overhead of multi-pass overwrite procedures.

Designed for compatibility with enterprise storage platforms from major brands, the Ultrastar DC HC560 supports third-party certified configurations across scale-out NAS, SAN, and JBOD enclosures. Its power profile, combining a low idle power draw with efficient seek performance, makes it well suited for hyperscale and colocation facilities where per-drive energy costs are a significant operational consideration. Omnixon Global supplies the WUH722020AL5205 to enterprise buyers across the UAE, GCC, EMEA, and APAC regions.

Ideal for

• Hyperscale and cloud object storage nodes requiring maximum raw capacity per rack unit with predictable sustained throughput
• AI and machine learning training data lakes where large sequential read workloads demand high-capacity, cost-efficient spinning media
• Enterprise backup and nearline archive systems where high workload ratings and long MTBF reduce replacement cycles in dense JBOD shelves
• Scale-out NAS deployments in media and entertainment environments storing and serving large unstructured file assets
• Surveillance and video analytics back-end storage requiring continuous 24×7 write workloads with stable thermal and power characteristics
• Secure data center refresh or drive redeployment scenarios leveraging Instant Secure Erase to meet compliance-driven data sanitization mandates
