0B36052 WD Ultrastar DC HC310 4TB SAS 256 MB 3.5" Server HDD

High-Performance 3.5in Enterprise SAS HDD for Always-On Storage Tiers with the 0B36052

The 0B36052 is a WD Ultrastar DC HC310 4TB 7.2K SAS enterprise hard drive engineered for predictable latency and sustained throughput in RAID arrays, JBOD shelves, and storage servers that operate 24/7. It targets general-purpose tiered storage where capacity efficiency and consistent service levels matter more than burst performance, while maintaining enterprise-class availability characteristics for dense multi-drive environments.

Architecturally, the 0B36052 combines CMR recording with a SAS transport designed for dual-port, multi-initiator topologies and storage controller integration. Support for 4Kn (with 512e compatibility options) helps align media format choices with modern filesystems and RAID controller sector handling, reducing translation overhead during rebuilds and large sequential operations. A 256MB cache supports command queue smoothing, while the 7200 RPM design balances access time and power for mixed backup, archive, and primary storage pools. For data-at-rest protection, the 0B36052 implements SED hardware encryption with TCG Enterprise SSC and FIPS 140-2 Level 2, enabling policy-driven key management without host-side performance penalties.

Why Choose the 0B36052?

The 0B36052 is a pragmatic choice for scaling capacity in enterprise bays where serviceability, predictable behavior under RAID workloads, and compliance-oriented security are required. It delivers a strong density-to-power profile for high-drive-count enclosures, supports straightforward fleet standardization, and is well suited to expanding backup repositories or tier-2 datasets without changing the storage architecture.

WD designs Ultrastar platforms around datacenter validation, vibration-aware operation in populated chassis, and reliability targets aligned with continuous duty cycles. This engineering focus supports integration with current SAS backplanes, controller feature sets, and operational processes common in enterprise data centres.
