0B26011 HGST Ultrastar C10K900 0.3TB SAS 64 MB 2.5" Server HDD

High-Performance 2.5in Enterprise SAS HDD for 24x7 Server and Array Duty Cycles with the 0B26011

The 0B26011 is an HGST Ultrastar C10K900 2.5in SAS enterprise HDD engineered as a high-IOPS rotating media tier for servers and storage arrays where predictable latency and serviceability matter. Designed for SAS backplanes and controller-managed environments, the 0B26011 integrates cleanly into SAS JBOD and RAID architectures as a boot/OS device or as a performance tier supporting mixed read/write workloads.

With a 10K-class spindle design and 64MB cache, the 0B26011 targets transactional I/O patterns that benefit from consistent queue handling rather than capacity density. Its single-port SAS interface aligns with standard dual-controller and expander topologies when deployed with appropriate pathing policies, while conserving bays for flash tiers. The 2.5in form factor improves storage density per rack unit and supports efficient airflow planning; low power draw (3W idle, 5.8W active) reduces thermal load in high-bay-count enclosures without compromising continuous-operation expectations.

Why Choose the 0B26011?

The 0B26011 is a practical choice when you need a reliable, service-friendly enterprise HDD for OS volumes, log targets, or tiered SAS pools in systems that must run continuously. In dense compute or storage nodes, the 0B26011 supports straightforward scaling by adding spindles for aggregate IOPS, while maintaining operational consistency across standardized 2.5in SAS slots and established RAID/JBOD deployment models.

HGST Ultrastar engineering focuses on sustained enterprise operation, controlled acoustics and thermals, and predictable behavior under load, aligning the 0B26011 with modern data center requirements for 24x7 availability, maintainability, and lifecycle-managed refresh planning.
