0B32258 WD Ultrastar SSD1600MR 200GB SAS 2.5" Server SSD

High-Performance 2.5-inch SAS Enterprise SSD for transactional tiers with the 0B32258

The 0B32258 is a WD/HGST Ultrastar SSD1600MR engineered for 24x7 internal server storage behind SAS backplanes, delivering predictable latency for mixed read/write transactional workloads and write-intensive caching or logging tiers. As a hot-swap 2.5-inch SAS drive, the 0B32258 aligns with standard enterprise drive bays and service procedures, enabling rapid replacement without disrupting host availability.

Architecturally, the 0B32258 pairs MLC NAND with a SAS interface to sustain consistent throughput and queue-depth behavior under virtualization and database activity, reaching up to 1100MB/s read and 700MB/s write. Its 4K performance up to 130k read IOPS and 30k write IOPS supports small-block IO patterns common in metadata, journaling, and transaction logs. With endurance rated at 3.288DWPD over 5 years and 1200TBW, the 0B32258 is positioned for write-heavy tiers while maintaining tight operational power envelopes at 2.2W idle and 11W active.

Why Choose the 0B32258?

The 0B32258 provides a balanced density-to-performance profile for SAS-based server fleets that standardize on hot-swap maintenance and predictable fail-in-place operations. By combining enterprise endurance, strong random IO characteristics, and compatibility with existing SAS backplane topologies, the 0B32258 scales cleanly from single-node storage to multi-bay arrays without introducing PCIe slot dependency.

WD designs Ultrastar enterprise SSDs with a focus on sustained reliability and data-center operational consistency, aligning firmware behavior and qualification practices to modern server platform requirements and continuous-duty environments.
