0B26014 WD Ultrastar C10K900 0.9TB SAS 64 MB 2.5" Server HDD

High-Performance 2.5in SAS Enterprise HDD for RAID and hot-swap bays with the 0B26014

The 0B26014 is a WD Ultrastar C10K900 2.5in SAS enterprise HDD designed for always-on datacentre duty cycles where predictable latency and serviceability matter more than peak sequential throughput. As a 10K-class, CMR-based drive, the 0B26014 aligns with RAID controller behaviour and rebuild processes, reducing the risk of timeouts commonly associated with non-CMR media in multi-drive arrays.

Architecturally, the 0B26014 targets the SAS HDD tier in mixed read/write environments such as virtualised infrastructure datastores, transactional application volumes, and general-purpose shared storage. The SAS interface supports dual-domain backplanes and hot-swap drive bays for resilient maintenance workflows, while the 64MB cache helps absorb short bursts and smooth write coalescing under typical enterprise queue depths. With an efficient power profile for a 2.5in 10K drive, the 0B26014 enables higher spindle density per chassis without disproportionately impacting thermal envelopes, making it suitable for dense 1U/2U storage servers and converged platforms.

Why Choose the 0B26014?

The 0B26014 provides a balanced density-to-performance profile for organisations that need consistent IOPS, operational predictability, and straightforward integration into existing SAS RAID arrays. By standardising on the 0B26014 across hot-swap pools, IT teams can simplify spares strategy, streamline firmware qualification, and scale capacity in granular increments while maintaining enterprise reliability expectations.

WD engineers the Ultrastar family for sustained 24x7 operation, focusing on controlled error recovery, array-friendly behaviour, and mechanical robustness suited to modern rack servers. The 0B26014 fits established data centre standards for serviceability and lifecycle management, supporting structured maintenance windows and resilient storage operations.

Key Applications:

• RAID arrays and SAS hot-swap drive bays
• Virtualisation datastores
• Transactional databases and logs
• General-purpose enterprise file and block storage
