0F38754 WD Ultrastar DC HC560 20TB SATA 512 MB 3.5" Server HDD

High-Capacity 3.5-inch Nearline Enterprise SATA HDD featuring SED security with the 0F38754

The 0F38754 is a WD Ultrastar DC HC560 20TB 3.5-inch SATA HDD designed for capacity-led server and JBOD tiers where throughput consistency and encrypted-at-rest compliance are mandatory. Built as a 7200RPM nearline drive, the 0F38754 targets scale-out storage nodes and dense shelves that require predictable behavior under sustained 24x7 duty cycles.

Architecturally, the 0F38754 aligns with SATA backplanes for broad compatibility while supporting 512e formatting for modern operating systems and array controllers. The drive’s CMR recording with EAMR and OptiNAND optimizes areal density without shifting write amplification patterns typical of SMR, which helps maintain steady rebuild and ingest performance. A 512MB cache supports burst handling and command queuing, while the 0F38754 remains focused on sequential and mixed streaming workloads typical of backup, archive, and content repositories.

Why Choose the 0F38754?

The 0F38754 delivers a practical density-to-bay ratio for nearline storage growth while embedding Self-Encrypting Drive capabilities for policy-driven data protection at rest. In large-scale deployments, the 0F38754 supports standardized SATA expansion and simplifies lifecycle operations through hardware-based security features, enabling consistent provisioning across nodes and predictable integration into existing storage architectures.

WD’s Ultrastar engineering emphasizes reliability under continuous operation, validated for enterprise thermal and vibration environments and aligned with modern data center qualification practices. With TCG Enterprise support and secure erase options, WD designs the 0F38754 to fit regulated retention workflows without adding software-layer encryption overhead to the storage stack.

Key Applications:

• Scale-out object storage nodes
• Backup and recovery repositories
• Archive and compliance retention tiers
• Content storage and media libraries
• JBOD expansion shelves
