0F38651

High-Capacity 3.5-inch Enterprise SAS HDD featuring encrypted bulk storage with the 0F38651

The 0F38651 is a WD Ultrastar DC HC560 20TB internal 3.5-inch HDD engineered for dense data centre storage where predictable throughput, high capacity per bay, and security controls are mandatory. Using 12Gb/s SAS connectivity with 4Kn media and 512e emulation, the 0F38651 integrates cleanly into enterprise backplanes and RAID controllers while supporting consistent addressing and alignment practices across mixed fleets.

Architecturally, the 0F38651 combines 7200 RPM CMR recording with EAMR to sustain write behaviour suited to rebuild-heavy RAID sets, backup tiers, and object storage nodes. A 512MB cache and OptiNAND assist metadata handling and performance stability under queue depth, while the helium platform and Triple Stage Actuator improve positioning accuracy for better array-level consistency. For regulated environments, the 0F38651 implements SED hardware encryption and Sanitize Crypto Erase to enable secure decommissioning without operational disruption.

Why Choose the 0F38651?

The 0F38651 delivers a strong capacity-to-slot ratio for scale-out designs, reducing rack footprint and controller ports per TB while keeping SAS manageability and enterprise serviceability. With 2.5M hours MTBF and support for modern data centre integration practices, the 0F38651 is built for predictable lifecycle planning, repeatable deployment in homogeneous drive groups, and scalable expansion across nodes and shelves.

WD designs Ultrastar platforms around continuous duty cycles, vibration-aware mechanics, and data centre operational standards. Features such as OCP 2.0 support and helium-based efficiency align WD engineering with modern fleet telemetry, power governance, and secure handling requirements across multi-tenant infrastructure.
