0B32281 HGST Ultrastar SSD1600MR 400GB SAS 2.5" Server SSD

High-Performance 2.5in Hot-Swap Enterprise SAS SSD for secure boot and cache tiers with the 0B32281

The 0B32281 is an HGST Ultrastar SSD1600MR-class enterprise SAS SSD engineered for consistent low-latency storage in 24/7 rack server and blade environments. Built on MLC NAND with a 2.5in hot-swap form factor, the 0B32281 targets OS, metadata, and read-intensive tiers where predictable response time matters more than peak burst throughput.

Architecturally, the 0B32281 leverages dual-port SAS to integrate cleanly into redundant storage fabrics and backplanes, enabling high availability for clustered hosts and shared storage shelves. With up to 1100 MB/s read, 700 MB/s write, and 4K performance up to 130k read and 30k write IOPS, it supports mixed virtualization and database workloads without the latency penalties typical of rotating media. Endurance is aligned to enterprise write profiles at 2 DWPD over 5 years (1460 TBW), while power behavior (2.2W idle, 11W active) supports dense deployments with controlled thermals.

Why Choose the 0B32281?

The 0B32281 provides a balanced density-to-performance ratio for boot, cache, and tiering use cases where service continuity and deterministic SAS behavior are required. By combining hot-swap serviceability, dual-port connectivity, and enterprise endurance, the 0B32281 scales from single-server OS volumes to multi-host pools without compromising operational maintenance windows.

HGST designs Ultrastar-class media with a focus on sustained reliability, predictable firmware behavior, and interoperability with modern data centre backplanes and SAS controllers. The platform aligns with enterprise lifecycle expectations through 2.0M hours MTBF and validated 24/7 duty-cycle operation.

Key Applications:

• Server boot and OS volumes
• Read-intensive cache and metadata tiers
• Virtualization datastores
• Low-latency database logging and indexing
• Secure multi-tenant deployments
