0B32146 WD Ultrastar SSD1600MM 800GB SAS 2.5" Server SSD

High-Performance 2.5-inch SAS Enterprise SSD for write-intensive tiers with the 0B32146

The 0B32146 is a 2.5-inch hot-swap SAS enterprise SSD designed for predictable latency and sustained throughput in shared storage and server platforms where queue depth, write persistence, and serviceability matter. As a SAS device, 0B32146 integrates cleanly into dual-controller backplanes and enterprise RAID/HBA topologies, supporting consistent behavior under mixed workloads typical of virtualisation and enterprise database tiers.

Built on MLC NAND, the 0B32146 targets cache, tiering, and 24x7 logging pipelines by balancing write endurance with stable 4K performance profiles. The architecture prioritises data-path efficiency and deterministic response over peak burst metrics, enabling array and cluster designs to maintain QoS under consolidation. With self-encrypting drive capabilities and TCG Enterprise support, 0B32146 also aligns with secure media handling requirements without introducing operational complexity during drive replacement.

Why Choose the 0B32146?

The 0B32146 delivers an enterprise density-to-performance ratio suited for all-flash arrays and scale-out server storage, combining hot-swap operability with SAS resilience and proven endurance for write-heavy tiers. By selecting 0B32146, infrastructure teams can scale capacity in small increments while maintaining uniform service levels across pools, and standardise secure drive handling across racks and sites.

WD engineers the 0B32146 for 24x7 data centre duty cycles, focusing on reliability, power discipline, and predictable long-term operation in standard 2.5-inch SAS bays. The design aligns with modern operational requirements for encrypted media, controlled replacement workflows, and compatibility across established enterprise storage stacks.

Key Applications:

• Read/write cache and tiering for all-flash arrays
• Mixed-use virtualisation storage
• Enterprise databases
• Write-intensive logging and analytics
