0F38755 WD Ultrastar DC HC560 20TB SATA 512MB 3.5" HDD

High-Capacity 3.5in Enterprise SATA HDD for Nearline and Scale-Out Storage with the 0F38755

The 0F38755 is a 20TB 3.5in internal enterprise HDD built for capacity-centric tiers where CPU and GPU acceleration is applied upstream, and storage consistency and predictable latency are critical. In WD Ultrastar DC HC560 platforms, the 0F38755 supports modern server architectures using high-core-count CPU nodes and GPU-assisted analytics by providing a dense SATA data layer for ingestion, backup, and object repositories without shifting cost to premium media.

Designed for broad compatibility, the 0F38755 integrates cleanly behind contemporary PCIe Gen4/Gen5 storage controllers and HBAs, feeding SATA backplanes in JBOD shelves and dense storage servers. CMR recording at 7200RPM with a 512MB cache helps sustain RAID rebuild behavior and sequential throughput profiles typical in scale-out and archive tiers. With 4Kn/512e sector formatting options, the 0F38755 supports alignment requirements across hypervisors and software-defined storage stacks while maintaining operational simplicity in mixed fleets.

Why Choose the 0F38755?

The 0F38755 delivers a strong density-to-bay ratio for nearline capacity expansion, enabling IT teams to scale object storage nodes and RAID arrays with fewer spindles and lower rack footprint. With enterprise-class MTBF targets and a workload focus aligned to bulk data, the 0F38755 is engineered for predictable deployment across multi-shelf SATA domains and serviceable, modular storage tiers.

WD engineering prioritizes datacenter reliability, consistent firmware behavior, and qualification for standard 3.5in hot-swap ecosystems. The platform aligns with modern operational requirements, including controlled power profiles, defined thermal ranges, and Secure Erase support for decommissioning workflows.

Key Applications:

• Nearline bulk storage tiers
• Backup and archive repositories
• Scale-out and object storage nodes
• RAID arrays in enterprise file storage
• SATA JBOD shelves and dense storage servers
