0B32186 HGST Ultrastar SSD1600MM 400GB SAS 2.5" Server SSD

High-End 2.5-inch SAS Hot-Swap Enterprise SSD for OS and Transactional Tiers with the 0B32186

The 0B32186 is a HGST Ultrastar SSD1600MM designed for latency-sensitive server OS and application tiers where consistent mixed read/write performance is required. Built on an enterprise MLC NAND architecture, the 0B32186 targets virtualization and database logging paths that need predictable QoS under sustained 24x7 load.

Using a 2.5-inch SAS interface, the 0B32186 integrates cleanly into dual-controller backplanes and standard hot-swap bays, enabling serviceability without disrupting host availability. Its I/O path is optimized for 4K random access patterns, supporting up to 130k/100k random read/write IOPS, while endurance is engineered for intensive duty cycles at 10 DWPD over 5 years (7,300 TBW). For security-focused deployments, the 0B32186 implements AES-256 hardware encryption with TCG Enterprise support, aligning data-at-rest protection with enterprise key management workflows.

Why Choose the 0B32186?

The 0B32186 delivers a balanced density-to-performance profile in a 400GB footprint, making it suitable for scaling OS volumes, boot pools, and write-intensive application logs across multiple nodes. With hot-swap serviceability, 2.0M hours MTBF, and controlled power behavior (2.2W idle, 11W active), the 0B32186 supports reliability-driven architectures where operational continuity and predictable maintenance windows matter.

HGST designs enterprise SSDs with an emphasis on sustained performance consistency, firmware stability, and qualification against data center interoperability requirements. The platform approach behind the 0B32186 aligns with modern rack and blade server standards, supporting continuous operation and lifecycle-managed deployments.
