WD Ultrastar DC HC580 28TB 3.5-inch SAS 12Gb/s 7200 RPM Enterprise Nearline HDD

The WD Ultrastar DC HC580 is Western Digital's 28TB 3.5-inch enterprise nearline hard drive, engineered on the company's ninth-generation HelioSeal platform with triple-stage actuator (TSA) technology. The drive utilizes OptiNAND architecture, integrating a tightly coupled iNAND flash device that works with the firmware to extend rotational vibration (RV) tolerance and enable journal-based caching for metadata, ultimately improving random write performance and overall drive responsiveness under demanding datacenter conditions. The SAS 12Gb/s interface delivers dual-port connectivity with full SAS protocol support, providing the path redundancy and error recovery capabilities that enterprise storage arrays require for continuous availability.

Operating at 7200 RPM across ten PMR (perpendicular magnetic recording) platters sealed in a helium-filled enclosure, the HC580 achieves a sustained data transfer rate that supports high-throughput sequential workloads without the increased power draw associated with air-filled designs. The HelioSeal construction reduces internal turbulence and drag, enabling higher areal density per platter while maintaining lower operating temperatures. The drive is rated for a workload of up to 550TB per year, reflecting its suitability for mixed read/write environments typical of large-scale object storage, cloud infrastructure, and active archive tiers.

The WD Ultrastar DC HC580 (manufacturer part number WUH722828AL5204) targets hyperscale and enterprise deployments where capacity efficiency, data integrity, and long-term reliability are primary requirements. With a 2.5 million hours mean time between failures (MTBF) rating and support for T10 PI (Protection Information) end-to-end data integrity, the drive is built to operate continuously in high-density JBOD and enterprise RAID enclosures. Its power management features, including low idle states, allow operators to optimize total cost of ownership across large drive populations in energy-conscious datacenter environments.

Ideal for

• Hyperscale object storage clusters requiring maximum raw capacity per rack unit with dual-port SAS redundancy
• AI and machine learning training data repositories where large sequential dataset ingestion and retrieval at sustained throughput is critical
• Cloud and colocation service providers building high-density nearline tiers for cold and warm data with long-term retention requirements
• Enterprise backup and recovery target storage, including disk-to-disk backup architectures and virtual tape library (VTL) back-ends
• Active archive and compliance storage platforms where data integrity verification via T10 PI and high MTBF ratings are mandatory
• Software-defined storage (SDS) deployments on platforms such as Ceph or IBM Spectrum Scale where per-drive capacity maximization reduces overall node count and infrastructure footprint
