0B36412 WD Ultrastar DC HC320 8TB SAS 256 MB 3.5" Server HDD

High-Density 3.5in SAS Datacenter HDD for RAID and Always-On Storage with the 0B36412

The 0B36412 is a WD Ultrastar DC HC320 8TB internal datacenter HDD built for predictable performance in enterprise RAID arrays and tiered SAN/NAS designs where sustained throughput and consistent latency are required. Using CMR recording and a 7200RPM spindle, the 0B36412 aligns well with write-intensive rebuild scenarios and mixed read/write workloads that can expose SMR penalties in capacity tiers.

Architected around a 12Gb/s SAS transport, the 0B36412 integrates cleanly into dual-ported backplanes, expander-based enclosures, and HBA-controlled storage nodes, enabling high availability and serviceability in dense 3.5in platforms. The 256MB cache supports command queue efficiency, while 4Kn media with 512e emulation simplifies compatibility across operating systems, hypervisors, and legacy storage stacks without sacrificing modern sector integrity. For compliance-oriented repositories, the 0B36412 includes Self-Encrypting Drive capabilities aligned to TCG Enterprise SSC and validated to FIPS 140-2 Level 2, supporting secure decommissioning and controlled data-at-rest protection.

Why Choose the 0B36412?

The 0B36412 delivers a balanced density-to-performance profile for scale-out storage nodes, backup targets, and archival tiers that still demand enterprise duty cycles. With a 2.0M-hour MTBF rating and datacenter power characteristics engineered for 24x7 operation, the 0B36412 supports predictable fleet behavior and straightforward capacity scaling across multi-bay enclosures.

WD Ultrastar engineering prioritizes reliability under continuous workloads, consistent firmware behavior for array environments, and alignment with modern datacenter standards for manageability, security, and integration in SAS-based storage architectures.

Key Applications:

• RAID arrays in 3.5in storage servers
• SAN/NAS capacity tiers
• Backup and restore repositories
• Compliance-oriented secure data retention
• Scale-out storage nodes with SAS backplanes
