0B32145 WD Ultrastar SSD1600MM 400GB SAS 2.5" Server SSD

Write-Intensive 2.5in SAS Enterprise SSD featuring SED security and hot-swap serviceability with the 0B32145

The 0B32145 is a 2.5in SAS enterprise SSD engineered for write-intensive tiers in server and storage platforms, combining predictable latency with consistent throughput under sustained random workloads. Using MLC NAND and an optimized SAS interface for dual-port backplanes, the 0B32145 supports high queue-depth IO patterns common in OLTP logging, metadata services, and cache/boot roles across virtualized clusters.

Designed for modern SAS infrastructure, the 0B32145 integrates seamlessly into hot-swap bays and shared storage enclosures, enabling non-disruptive maintenance and rapid replacement cycles. Its endurance profile supports continuous 24/7 operation with 10 DWPD over 5 years, while performance characteristics (up to 1100 MB/s read, 765 MB/s write and strong 4K IOPS) align with write-heavy transaction streams and mixed enterprise consolidation. Integrated SED with AES-256 and TCG Enterprise helps meet data-at-rest requirements without adding CPU overhead at the host.

Why Choose the 0B32145?

The 0B32145 delivers a balanced density-to-performance ratio for SAS-based fleets that require sustained write endurance, operational resilience, and secure lifecycle management. By keeping to a 2.5in hot-swap service model, the 0B32145 scales cleanly from single-server boot tiers to larger SAS backplanes, supporting standardized sparing, consistent performance, and simplified change control in enterprise environments.

WD designs Ultrastar enterprise SSDs with a reliability-first approach, aligning firmware behavior, power characteristics, and qualification processes to data centre availability targets. Built for continuous duty cycles, the platform integrates proven controller validation and robust MTBF expectations for infrastructure that must remain predictable under mixed IO and maintenance events.

Key Applications:

• Write-intensive databases and OLTP logging
• Virtualization boot and cache tiers
• SAS backplane hot-swap storage pools
• Metadata and journal acceleration
