0B32261 WD Ultrastar SSD1600MR 500GB SAS 2.5" Server SSD

High-Performance 2.5in SAS Hot-Swap Enterprise SSD for Read-Optimized Tiers with the 0B32261

The 0B32261 is a WD Ultrastar SSD1600MR 2.5in SAS hot-swap enterprise SSD engineered for server-qualified, dual-port SAS infrastructures where predictable latency and serviceability are mandatory. Its MLC NAND and controller behavior are tuned for read-intensive database acceleration, boot, and metadata tiers that must remain stable under 24x7 duty cycles.

Architecturally, 0B32261 integrates cleanly into existing SAS backplanes without redesigning the host PCIe topology, making it a practical upgrade path for platforms that prioritize high availability over NVMe-only layouts. With up to 1100 MB/s sequential read and up to 130K 4K read IOPS, it supports fast boot storms, catalog lookups, and index-heavy workloads, while write behavior up to 700 MB/s and 30K 4K write IOPS fits mixed read/write caching where SAS dual-port ecosystems are required. Endurance is specified at 2.63 DWPD over 5 years and 2400 TBW, supported by a 2.0M-hour MTBF profile and efficient power characteristics for dense 2.5in bays.

Why Choose the 0B32261?

The 0B32261 delivers a disciplined density-to-performance ratio for SAS estates, enabling consistent acceleration within hot-swap service models and dual-path storage designs. It scales cleanly across clustered servers, supports maintenance without downtime, and reduces operational risk by keeping performance and endurance aligned to read-optimized enterprise tiers.

WD designs Ultrastar enterprise SSDs with a reliability-first engineering philosophy, emphasizing qualification for server and storage subsystems, sustained QoS under continuous workloads, and alignment with modern data centre expectations for availability, power governance, and lifecycle consistency.

Key Applications:

• Read-intensive database acceleration
• Boot and OS/application SSD tiers
• Virtualization datastore and metadata
• Mixed read/write caching in SAS dual-port arrays
