0B36019 WD Ultrastar DC HC310 4TB SAS 256 MB 3.5" Server HDD

High-Performance 3.5in SAS Datacenter HDD featuring secure 4Kn capacity tiers with the 0B36019

The 0B36019 is a WD Ultrastar DC HC310 4TB internal datacenter HDD engineered for predictable latency and sustained throughput in SAS JBOD and RAID environments. Designed as a bulk-capacity building block, the 0B36019 supports 24x7 duty cycles while maintaining consistent behavior under mixed I/O typical of virtualisation, database logging, and scale-out storage nodes.

With a single-port SAS interface and CMR recording, the 0B36019 aligns well with enterprise backplanes and expander topologies where deterministic write characteristics matter for rebuild operations and long sequential streams. The 4Kn native sector format improves efficiency in modern storage stacks that are 4K-aligned, reducing translation overhead and supporting large-block workloads. A 7200RPM spindle and 256MB cache provide balanced performance for capacity tiers, while self-encrypting drive capabilities enable secure-at-rest architectures without consuming host CPU cycles. The 0B36019 further integrates into compliance-driven environments through TCG Enterprise SSC and FIPS 140-2 Level 2 support for hardware-based encryption workflows.

Why Choose the 0B36019?

The 0B36019 delivers a pragmatic density-to-performance ratio for enterprise arrays where cost-efficient capacity, rebuild resilience, and operational consistency are priorities. By combining 4Kn formatting with SAS integration and hardware encryption, the 0B36019 scales cleanly across multi-shelf deployments while supporting reliability targets aligned to continuous operation.

WD engineers Ultrastar platforms for datacenter serviceability, controlled acoustics and power behavior, and long-life validation against modern storage standards. This approach helps ensure predictable interoperability in heterogeneous racks and sustained reliability profiles expected in enterprise storage tiers.

Key Applications:

• SAS JBOD and RAID arrays
• Scale-out storage nodes
• Virtualisation capacity tiers
• Database backup and log repositories
• Compliance-focused encrypted storage
