0F38581

High-Capacity 3.5-inch Datacenter HDD for Scale-Out Storage Nodes with the 0F38581

The 0F38581 is a WD Ultrastar DC HC550 14TB 3.5-inch SATA HDD engineered for capacity-first server and storage expansion where predictable throughput and consistent latency matter more than peak IOPS. As a 7200RPM CMR drive, the 0F38581 supports steady write behavior under sustained ingest, making it suitable for object storage and data lake nodes that rely on stable rebuild and rebalancing performance.

Designed for broad platform compatibility, the 0F38581 integrates through a standard SATA interface and leverages a 512MB cache to smooth burst workloads while maintaining deterministic bulk-transfer characteristics. The 4Kn native format with 512e emulation simplifies alignment with modern operating systems and storage controllers, supporting efficient block management in mixed fleets. For dense JBOD and scale-out chassis, the 0F38581 incorporates rotational vibration safeguards to protect performance consistency across multi-bay deployments.

Why Choose the 0F38581?

The 0F38581 delivers an efficient density-to-power profile for warm and cold data tiers, enabling higher capacity per rack unit while keeping operational power under control. With datacenter-grade 24x7 duty design and a 2.5M-hour MTBF target, the 0F38581 aligns with enterprise reliability expectations for large pools where drive count and serviceability define overall risk and scaling cost.

WD applies a conservative engineering approach focused on long-life mechanics, workload stability, and platform interoperability for modern data centre standards. The Ultrastar portfolio emphasizes predictable behavior at scale, enabling consistent fleet management policies across backup, archive, and content repository environments.

Key Applications:

Backup and archive repositories
Object storage nodes
Data lake capacity tiers
Scale-out NAS expansion
Content repositories
