0B32185 WD Ultrastar SSD1600MM 200GB SAS 2.5" Server SSD

High-Performance 2.5in Enterprise SAS SSD for boot and cache tiers with the 0B32185

The 0B32185 is a 2.5in hot-swap enterprise SAS SSD engineered for consistent low-latency service in server boot/OS volumes, metadata acceleration, and write-intensive logging. By pairing a SAS interface with MLC NAND, the 0B32185 targets predictable performance under mixed I/O, minimizing tail latency that can impact OLTP and virtualization control planes.

Architecturally, the 0B32185 fits cleanly into standard SAS backplanes and RAID/HBA topologies, simplifying deployment in existing platforms while improving responsiveness versus spinning media in cache and journal roles. With up to 1100 MB/s read and 765 MB/s write plus strong 4K performance, the 0B32185 supports fast boot storms, VM metadata lookups, and sustained small-block writes, while endurance of 9.863 DWPD over 5 years is aligned to high-churn logging datasets. The 0B32185 also integrates self-encryption using AES-256 with TCG Enterprise compliance to support secure repurposing and policy-driven data-at-rest controls.

Why Choose the 0B32185?

The 0B32185 delivers an enterprise-ready density-to-performance profile for capacity-efficient tiers where latency and write endurance matter more than raw TB. Designed for 24x7 duty cycles with 2.0M hours MTBF, the 0B32185 scales across multi-node deployments by standardizing on hot-swap serviceability, consistent SAS behavior, and security controls that reduce operational risk in regulated environments.

WD focuses on durable storage engineering for always-on data centers, combining qualification for continuous operation with firmware behavior tuned for predictable service under sustained load. WD enterprise drives are designed to integrate with modern SAS infrastructure standards and lifecycle processes, supporting controlled rollouts and stable long-term operation.
