0B32259 WD Ultrastar SSD1600MR 400GB SAS 2.5" Server SSD

High-Performance 2.5-inch SAS Enterprise SSD for hot-swap server bays with the 0B32259

The 0B32259 is a WD Ultrastar SSD1600MR engineered for boot, read-intensive, and mixed enterprise storage tiers where consistent latency matters more than peak capacity. Built on MLC NAND and delivered in a 2.5-inch SAS hot-swap form factor, the 0B32259 integrates cleanly into high-availability server backplanes and shared storage enclosures that rely on dual-port SAS paths for resilient access.

Architecturally, the 0B32259 targets predictable performance under multi-queue I/O, supporting sequential throughput up to 1100 MB/s read and 700 MB/s write, with 4K random capability up to 130,000 IOPS read and 30,000 IOPS write. This profile fits OS volumes, VM boot pools, metadata acceleration, and read-dominant databases, while maintaining controlled write endurance at 2 DWPD over 5 years (1,460 TBW). With 2.0M hours MTBF and a power envelope of 2.2W idle and 11W active, it supports dense deployments where thermal and power budgets are tightly managed.

Why Choose the 0B32259?

The 0B32259 provides a practical density-to-performance ratio for enterprise racks by combining SAS hot-swap serviceability with endurance appropriate for mixed workloads. Deploying the 0B32259 standardizes boot and tier-1 read storage across nodes, simplifies spares strategy, and supports scalable rollouts in clustered servers that require rapid replacement without downtime.

WD designs Ultrastar enterprise SSDs with a focus on sustained workload reliability, conservative endurance ratings, and compatibility with modern SAS infrastructures used in data centres. The 0B32259 aligns with 24/7 operational expectations through validated firmware behavior, consistent QoS, and predictable lifecycle characteristics.

Key Applications:

• Server boot drives
• Virtualization boot and cache tiers
• Read-intensive databases
• High-availability hot-swap storage bays
