0B32070 WD Ultrastar SSD800MH.B 400GB SAS 2.5" Server SSD

High-Performance 2.5-inch SAS Enterprise SSD for predictable latency and hot-swap serviceability with the 0B32070

The 0B32070 is a 2.5-inch enterprise SAS SSD engineered for controller-based storage arrays and SAS server backplanes where consistent QoS matters more than peak burst speed. In mixed CPU virtualization hosts and dual-controller storage shelves, the SAS interface enables robust multipathing and deterministic failover behavior, making the 0B32070 suitable for 24/7 datacenter operation with predictable latency targets.

Built on MLC NAND, the 0B32070 focuses on endurance and sustained performance under steady-state conditions. Its 6Gb/s-class SAS architecture supports reliable hot-swap maintenance and slot-to-slot service continuity, while the drive’s performance envelope is aligned to read-intensive tiering and write-heavy metadata paths such as logs and cache. The combination of high 4K IOPS and strong sequential throughput allows the 0B32070 to reduce queue depth pressure on shared SAS expanders and to stabilize response times in consolidated environments.

Why Choose the 0B32070?

The 0B32070 delivers an enterprise-balanced density-to-performance profile in 400GB, optimized for SAS infrastructures that prioritize availability, path redundancy, and operational predictability. With endurance rated at 25 DWPD over 5 years and reliability engineered for continuous duty cycles, the 0B32070 fits scale-out deployments where fleet consistency, hot-swap workflows, and stable latency under load are essential.

WD designs Ultrastar-class SSDs with a focus on datacenter validation, long-life firmware stability, and compatibility with common SAS RAID/HBA ecosystems. The platform targets enterprise reliability requirements, supporting modern rack and storage standards where serviceability and sustained performance are baseline expectations.

Key Applications:

• SAS server and storage array tiering
• Database log and journal volumes
• Read-intensive VDI and virtualization datastores
