0B36406 WD Ultrastar DC HC320 8TB SAS 256 MB 3.5" Server HDD

High-Density 3.5in Datacenter SAS HDD with Self-Encrypting Security using the 0B36406

The 0B36406 is a WD Ultrastar DC HC320 enterprise hard drive engineered for primary storage tiers in servers and storage arrays where predictable throughput, consistent latency, and 24x7 duty-cycle operation are mandatory. Built around 7200RPM mechanics and a 256MB cache, the 0B36406 is optimized for sustained read/write behavior across mixed block workloads typical of virtualization, backup repositories, and data lake staging.

With CMR recording and 4Kn media support while maintaining 512e compatibility, the 0B36406 aligns with modern OS and hypervisor storage stacks that require efficient sector handling and reduced write amplification. The single-port SAS interface targets enterprise backplanes and RAID/HBA architectures, enabling scalable expansion across dense 3.5in bays and consistent performance under queue depth. For security-sensitive environments, the 0B36406 integrates hardware-based self-encrypting drive capabilities compliant with TCG Enterprise SSC to support controlled decommissioning and secure multi-tenant operations.

Why Choose the 0B36406?

The 0B36406 delivers a balanced density-to-reliability profile for capacity-forward tiers, combining enterprise SAS integration with encryption at the device layer to simplify compliance without adding CPU overhead. Designed for array scale-out, the 0B36406 supports predictable fleet behavior and serviceability in standardized datacenter chassis, helping IT teams expand capacity while maintaining operational consistency.

WD designs Ultrastar platforms with a focus on datacenter endurance, controlled vibration behavior, and qualification for continuous operation. This engineering approach aligns the 0B36406 with enterprise lifecycle requirements, including secure handling policies and compatibility with established SAS storage ecosystems.
