0F38462 WD Ultrastar DC HC550 16TB SATA 512 MB 3.5" Server HDD

High-Density 3.5-inch Enterprise SATA HDD for Capacity-Optimised Data Centre Storage with the 0F38462

The 0F38462 is a 16TB WD Ultrastar DC HC550 internal 3.5-inch enterprise HDD engineered for capacity-focused server storage where predictable throughput, sustained duty cycles, and consistent latency matter more than peak IOPS. Deployed behind modern RAID/HBA controllers and scale-out storage software, the 0F38462 supports dense storage nodes that prioritise cost-efficient terabytes per rack unit while maintaining data centre operational stability.

Using a SATA interface with 4Kn/512e sector format support, the 0F38462 integrates cleanly into existing backplanes and hot-swap bays, enabling straightforward expansion across PCIe-attached controllers without changing chassis standards. EAMR with TDMR, a triple stage actuator, and rotational vibration safeguards are designed to protect track-follow accuracy in multi-drive enclosures, while 7,200 RPM operation and 512MB cache balance sequential performance for backup windows, object storage ingest, and archive retrieval patterns. The absence of SED support positions the 0F38462 for environments where encryption is handled at the platform, volume, or application layer.

Why Choose the 0F38462?

The 0F38462 provides a strong density-to-reliability profile for capacity tiers, enabling scalable growth in RAID groups and scale-out nodes without forcing architectural changes. With 24x7 duty cycle design and 2.5M hours MTBF, the 0F38462 supports predictable fleet behaviour across large deployments, helping storage architects standardise drive classes for backup, archive, and object repositories.

WD designs Ultrastar platforms with a focus on data centre qualification, sustained operation, and mechanical control features that support multi-bay vibration conditions. The result is an enterprise HDD portfolio aligned to modern server and storage standards where serviceability, interchangeability, and long lifecycle planning are operational requirements.
