0B31074 WD Ultrastar SSD1600MR 250GB SAS 2.5" Server SSD

Enterprise 2.5in SAS SSD for boot and cache tiers with the 0B31074

The 0B31074 is a WD Ultrastar SSD1600MR 2.5in SAS internal enterprise SSD engineered for OS boot volumes, read-heavy caching, and mixed transactional profiles in servers and storage arrays. Using a 12Gb/s-class SAS interface, the 0B31074 integrates cleanly into dual-ported backplanes and RAID/HBA designs where deterministic latency and predictable serviceability matter.

Architecturally, the 0B31074 uses 250GB MLC NAND and a controller design without DRAM cache, reducing component complexity while maintaining stable behavior for boot and cache roles. The SAS transport enables robust error handling and multi-pathing, supporting high-availability topologies and maintenance workflows. With performance up to 1100 MB/s read and 700 MB/s write and 4K responsiveness aligned to read-dominant access, the 0B31074 targets platform efficiency rather than oversized capacity. Endurance rated at 2.6 DWPD over 5 years and reliability at 2.0M hours MTBF help standardize lifecycle planning across fleet deployments.

Why Choose the 0B31074?

The 0B31074 delivers an efficient density-to-performance balance for 2.5in drive bays, enabling fast boot consolidation and cache acceleration without consuming high-capacity slots. For enterprise environments, the 0B31074 supports scalable rollouts through SAS compatibility, consistent operational characteristics, and predictable endurance sizing for mixed I/O tiers.

WD designs Ultrastar enterprise SSDs with a focus on controlled behavior under sustained workloads, qualification for data center operating conditions, and interoperability with common server and storage architectures. This approach supports repeatable deployment standards and reduces validation effort in compliance-bound infrastructure.

Key Applications:

• OS boot drives for rack servers
• Read-heavy cache tier in storage arrays
• Virtualization host boot and metadata acceleration
• Mixed transactional workloads with moderate write endurance
• Compliance-bound secure storage with hardware encryption
