0F38784 WD Ultrastar DC HC560 20TB SATA 3.5" Server HDD

High-Density 3.5in Datacenter SATA HDD Storage featuring helium CMR architecture with the 0F38784

The 0F38784 is a 20TB 3.5in internal datacenter HDD engineered for high-capacity SATA tiers in enterprise servers and storage arrays where predictable latency and sustained throughput matter more than flash-level IOPS. As a WD Ultrastar DC HC560 platform drive, it aligns with modern x86 CPU-based storage servers and JBOD/JBOF enclosures that rely on host-side compute for data services, while keeping cost-per-terabyte optimized for bulk capacity.

Using helium-filled mechanics and CMR recording with 4Kn media (512e emulation), the 0F38784 supports consistent write behavior for rebuilds, replication, and sequential ingest typical of object storage and data lakes. The SATA interface integrates cleanly behind standard HBAs and expander backplanes, and the 7200RPM design balances queue-depth handling with controlled power draw for dense racks. For security-sensitive environments, the 0F38784 provides Self-Encrypting Drive capabilities with Sanitize Crypto Erase to streamline decommissioning workflows without disrupting operational processes.

Why Choose the 0F38784?

The 0F38784 delivers a practical density-to-bay ratio for always-on infrastructures, enabling capacity expansion without additional chassis or rack footprint. Its datacenter-class endurance profile supports 24x7 duty cycles, while the 0F38784 scales predictably in large SATA pools for backup, archive, and warm data platforms where reliability and serviceability are primary design constraints.

WD engineers the Ultrastar family with an emphasis on sustained operation, controlled vibration behavior, and enterprise qualification processes that map to modern data centre standards. With the 0F38784, that philosophy translates into a drive suited for long-life deployments and consistent fleet management practices.
