0B36032 WD Ultrastar DC HC310 4TB SATA 256 MB 3.5" Server HDD

High-Density 3.5in Enterprise SATA HDD for Datacenter RAID and JBOD Storage with the 0B36032

The 0B36032 is a 3.5in internal WD Ultrastar DC HC310 enterprise HDD designed for consistent throughput and predictable latency in always-on storage stacks. As a SATA platform drive, the 0B36032 aligns with cost-efficient server backplanes and storage shelves where bandwidth is aggregated across many spindles rather than a single PCIe-attached device.

Built on CMR media at 7200 RPM with 512n sector format and 256MB cache, the 0B36032 supports steady write behavior that is critical for RAID rebuilds and mixed random/sequential patterns common in virtualization datastores, file services, and general-purpose server volumes. The SATA interface simplifies integration in existing SAS expanders, HBA-based JBOD designs, and dense bays, while SED hardware encryption with TCG Enterprise SSC enables policy-driven data-at-rest protection without host CPU overhead.

Why Choose the 0B36032?

The 0B36032 delivers an enterprise-balanced density-to-performance profile for 24/7 arrays, offering operational stability for large drive counts and predictable scaling when capacity is increased by adding bays or shelves. With a 2.0M-hour MTBF target and datacenter-class power characteristics, the 0B36032 is well suited for standardized fleet deployments where lifecycle consistency and serviceability matter as much as raw capacity.

WD engineers Ultrastar platforms with a focus on sustained duty cycles, controlled vibration tolerance in multi-drive enclosures, and qualification against modern server and storage interoperability requirements. This reliability-first approach supports repeatable deployments across rack servers, NAS appliances, and SATA JBOD tiers.

Key Applications:

• 24/7 RAID arrays in rack servers
• SATA JBOD backup and archive tiers
• NAS and on-prem file services
• General-purpose server primary storage
