0B31068 HGST Ultrastar SSD1600MM 1.6TB SAS 2.5" Server SSD

High-Performance 2.5-Inch SAS Enterprise SSD for Mixed Random I/O and Tiered Acceleration with the 0B31068

The 0B31068 is a 1.6TB 2.5-inch hot-swap SAS enterprise SSD engineered to stabilise latency and raise IOPS ceilings in shared storage and server bays where consistent mixed read/write behaviour is required. Built on MLC NAND, the 0B31068 targets boot, log, metadata, and caching tiers that sit closest to transactional workloads, reducing queue depth sensitivity and improving service-time predictability under consolidation.

With a SAS interface optimised for dual-port enterprise backplanes, the 0B31068 integrates cleanly into existing RAID and HBA architectures while maintaining strong sequential throughput and 4K random performance for OLTP and virtualisation storage. Endurance is sized for sustained write activity at 10 DWPD over 5 years, supporting write-intensive caching and journal patterns without premature wear constraints. For secured environments, the 0B31068 includes Self-Encrypting Drive (SED) capability to align with at-rest protection policies while preserving operational simplicity during drive replacement.

Why Choose the 0B31068?

The 0B31068 provides a practical density-to-performance profile for enterprises standardising on 2.5-inch hot-swap SAS bays, delivering predictable acceleration where boot storms, metadata contention, or OLTP log pressure can limit platform efficiency. The 0B31068 is designed for 24x7 operation with high MTBF expectations and power characteristics suitable for dense chassis, enabling scalable deployment across clustered nodes and tiered arrays without re-architecting the storage fabric.

HGST engineering focuses on enterprise duty-cycle reliability, consistent firmware behaviour, and controlled latency under sustained load. The 0B31068 aligns with modern data centre requirements for serviceability, secure disposal workflows, and repeatable performance in standard SAS infrastructures.

Key Applications:

• Read/write caching tiers
• OLTP databases
• Virtualisation storage
• Server boot, log, and metadata volumes
• Mixed random I/O acceleration
