0B31072 WD Ultrastar SSD800MH.B 800GB SAS 2.5" Server SSD

High-Endurance 2.5in SAS Enterprise SSD for Mixed Workloads with the 0B31072

The 0B31072 is an 800GB 2.5in SAS enterprise SSD engineered for predictable latency and sustained write behavior in server and storage array architectures. Designed for hot-swap backplanes, it integrates cleanly into RAID groups and shared storage shelves where serviceability and rapid replacement cycles are operational requirements.

With MLC NAND and a high-endurance profile, the 0B31072 supports write-intensive database logging, virtualization caching, and mixed read/write tiering where steady-state performance matters more than peak burst metrics. SAS connectivity provides deterministic command handling and dual-path capable designs in many enterprise enclosures, while performance up to 1100 MB/s read, 765 MB/s write, and 4K IOPS up to 130K/110K aligns with consolidation targets for transactional VMs and high-IO metadata workloads. For data-at-rest protection, the 0B31072 implements Self-Encrypting Drive (SED) functionality to fit security-controlled storage domains.

Why Choose the 0B31072?

The 0B31072 delivers a density-to-endurance balance suited to 24x7 RAID and array duty cycles, enabling higher write budgets per bay without sacrificing operational continuity. Its hot-swap design supports scalable fleet operations, while 2.0M hours MTBF and controlled power characteristics (2.2W idle, 11W active) help maintain reliability and thermal predictability in dense storage nodes.

WD engineers the Ultrastar SSD portfolio for enterprise qualification, emphasizing consistent firmware behavior, long-life endurance modeling, and compatibility with modern data centre maintenance practices. This approach helps the 0B31072 integrate into standardised lifecycle management, secure handling processes, and performance validation workflows.

Key Applications:

• Virtualization caching and tiering
• Write-intensive databases and logging
• 24x7 enterprise storage arrays
• RAID groups in shared SAS enclosures
• Mixed read/write server storage
