0B36452 WD Ultrastar DC HC320 8TB SATA 256 MB 3.5" Server HDD

Datacenter-Class 3.5-inch Enterprise HDD for Capacity Tiers with the 0B36452

The 0B36452 is a WD Ultrastar DC HC320 8TB internal 3.5-inch enterprise HDD engineered for 24/7 datacenter duty cycles where predictable latency and sustained throughput matter more than burst performance. Using CMR recording and a 7200 RPM mechanical platform, the 0B36452 supports consistent write behavior for RAID rebuilds and heavy background scrubbing, reducing risk in multi-drive pools.

Designed for SATA storage fabrics, the 0B36452 integrates cleanly into bulk-capacity tiers, JBOD expansion shelves, and single-port backplanes without introducing protocol complexity. Its 4Kn format with 512e emulation helps align with modern OS and hypervisor storage stacks while maintaining compatibility for mixed deployments. A 256MB cache supports steady streaming and metadata operations, making the 0B36452 suitable for dense nearline architectures where power-efficient, high-capacity spindles scale out behind controllers and HBAs.

Why Choose the 0B36452?

The 0B36452 provides a practical density-to-reliability profile for enterprise storage nodes that need repeatable behavior under continuous load. With datacenter-class endurance targets and a 2.0 million hour MTBF rating, the 0B36452 is positioned for scalable capacity growth across RAID arrays and distributed storage pools while keeping service procedures and spares management straightforward.

WD builds Ultrastar platforms with an engineering focus on operational stability, firmware consistency, and lifecycle suitability for standardized data centre environments. The 0B36452 aligns with common rack-scale storage designs that prioritize predictable integration, secure sanitization support, and long-term fleet uniformity.

Key Applications:

• Enterprise storage nodes and bulk SATA tiers
• RAID arrays and JBOD expansion
• Virtualisation and private cloud datastores
• Backup and archive repositories
