0B31075 WD Ultrastar SSD1600MR 400GB SAS 2.5" Server SSD

High-Performance 2.5-inch SAS Enterprise SSD for Read-Intensive Tiering with the 0B31075

The 0B31075 is a 2.5-inch hot-swap SAS enterprise SSD engineered for predictable latency in server caching, tiering, and mixed virtualised workloads. Built on MLC NAND, it balances sustained write capability with fast read response, aligning well with storage stacks that prioritise steady QoS under 24x7 utilisation rather than burst-only benchmarks.

With SAS connectivity, the 0B31075 integrates cleanly into dual-path enterprise backplanes and RAID/HBA topologies, supporting serviceable, front-access deployment in dense racks. Its architecture targets queue-depth efficiency for transactional access patterns, while sequential throughput supports log shipping, ingest, and rebuild operations. Hardware-based Self-Encrypting Drive (SED) capability enables encryption without shifting overhead to host CPU resources, helping maintain deterministic performance during secure multi-tenant operation.

Why Choose the 0B31075?

The 0B31075 delivers a practical density-to-performance profile for data centres that need consistent I/O behaviour, defined endurance, and predictable operational characteristics across large fleets. It is designed for scalable rollouts where hot-swap serviceability, enterprise SAS resiliency, and long-duty-cycle reliability reduce operational risk and simplify lifecycle maintenance in shared storage and server-local tiers.

WD applies an enterprise engineering philosophy focused on controlled firmware behaviour, validation under continuous workloads, and alignment with modern data centre standards for reliability, security, and manageability. For architects standardising platforms, WD enterprise SSDs are built to integrate into established SAS infrastructures while maintaining consistent latency characteristics over time.

Key Applications:

• Read-intensive server caching and tiering
