0B31078 HGST Ultrastar SSD1600MR 1TB SAS 2.5" Server SSD

High-Performance 2.5in SAS Enterprise SSD featuring SED security and read-optimised I/O with the 0B31078

The 0B31078 is an HGST Ultrastar SSD1600MR 1.92TB 2.5in SAS hot-swap drive engineered for read-intensive OLTP and mixed virtualisation storage where consistent latency and predictable service levels matter. Built on enterprise MLC NAND, the architecture targets high random read throughput while maintaining controlled write behaviour, aligning well with metadata-heavy platforms and cache tiers.

Using a dual-port SAS interface, the 0B31078 supports redundant paths and standard server backplanes for high-availability designs, enabling non-disruptive replacement and streamlined maintenance in dense chassis. The storage stack is optimised for high IOPS and sustained bandwidth, with a controller and firmware profile tuned for 24x7 datacentre duty cycles. For security-sensitive deployments, the 0B31078 integrates hardware-based self-encrypting drive capability to enforce encryption-at-rest without imposing host CPU overhead, supporting compliance-driven environments.

Why Choose the 0B31078?

The 0B31078 delivers a practical density-to-performance balance for enterprise servers that need fast reads, predictable queue handling, and operational continuity through hot-swap and dual-port SAS. Its endurance profile and enterprise reliability targets make it suitable for scalable VM clusters and database tiers where capacity expansion must not compromise service stability.

HGST designs Ultrastar-class storage for controlled thermals, consistent firmware behaviour, and long-life operation in standardised rack environments, supporting disciplined change management and measurable reliability objectives across modern SAS-based infrastructure.

Key Applications:

• Read-intensive OLTP databases
• Virtual machine datastores
