0B32232 WD Ultrastar SSD1600MR 400GB SAS 2.5" Server SSD

High-Performance 2.5-inch Enterprise SAS SSD for boot and cache tiers with the 0B32232

The 0B32232 is a 400GB 2.5-inch hot-swap SAS SSD designed to modernize legacy SAS HDD bays while maintaining predictable behavior across mixed read/write transactional storage. In server architectures where CPU and memory resources are underutilized by storage latency, the 0B32232 shifts boot volumes and cache tiers to low-latency flash, improving service responsiveness without changing the host platform.

Built on MLC NAND, the 0B32232 balances sustained write stability with enterprise endurance at 2 DWPD across a 5-year duty cycle, aligning with 24/7 datacentre operation. The SAS interface integrates cleanly with existing backplanes and RAID/HBA topologies, enabling straightforward PCIe preservation for expansion devices while still delivering up to 1100 MB/s read, 700 MB/s write, and up to 130k/30k IOPS (4K) read/write. For security-sensitive deployments, the 0B32232 implements hardware AES-256 encryption with TCG Enterprise SED capabilities to support controlled decommissioning and policy-driven access in shared infrastructure.

Why Choose the 0B32232?

The 0B32232 provides a high-density, drop-in SAS SSD option for enterprise estates that require consistent transactional performance, hot-swap serviceability, and reliability aligned to always-on operations. By targeting boot, caching, and active metadata tiers, the 0B32232 helps reduce recovery times and smooths peak I/O without forcing disruptive chassis or fabric redesigns.

WD engineers Ultrastar platforms for sustained datacentre workloads, focusing on firmware consistency, power-aware behavior, and long-life operation in multi-drive enclosures. With enterprise qualification and robust lifecycle management, WD storage aligns with standard SAS operational models and secure asset-handling requirements.
