0B32144 WD Ultrastar SSD1600MM 200GB SAS 2.5" Server SSD

High-Performance 2.5in SAS Enterprise SSD for Hot-Swap Arrays and Mixed I/O Caching with the 0B32144

The 0B32144 is a 2.5in SAS, hot-swap enterprise SSD engineered for predictable latency in RAID backplanes and SAS storage arrays where sustained mixed I/O is common. Built on MLC NAND and tuned for read/write caching and tiering, the drive supports consistent service levels in 24/7 environments while maintaining operational headroom for bursty workloads such as VM storage and database logging.

With a dual-port SAS interface for high-availability paths and simplified multipath design, 0B32144 integrates cleanly into enterprise enclosures and controller architectures. Its performance envelope (up to 1100 MB/s read and 765 MB/s write, with strong 4K IOPS) aligns with metadata-heavy operations and write-intensive log streams. Endurance is designed for sustained write cycles at 9.863 DWPD over 5 years, and power behavior supports dense deployments where thermal and per-slot power budgets matter.

Why Choose the 0B32144?

The 0B32144 provides a balanced density-to-performance profile for SAS infrastructures that require hot-swap serviceability, deterministic behavior, and scalable fleet deployment. It is well suited for building resilient tiers in shared storage, improving cache hit rates, and stabilizing latency under contention, while maintaining enterprise reliability targets for continuous duty cycles.

WD designs Ultrastar-class SSDs with a focus on data centre interoperability, sustained workload consistency, and lifecycle stability. The platform emphasizes validated firmware behavior, robust error handling, and alignment with standard SAS backplane and RAID controller ecosystems for predictable integration.

Key Applications:

• SAS array caching and tiering
• Mixed I/O database logging
• Virtualization and VM datastores
• 24/7 enterprise RAID backplanes
