0B25168 WD Ultrastar C10K1200 1.2TB SAS 64 MB 2.5" Server HDD

High-Performance 2.5in SAS Enterprise HDD for 24x7 Server and Array Duty with the 0B25168

The 0B25168 is a WD Ultrastar C10K1200 Series 1.2TB 10K RPM class internal SAS hard drive engineered for dense data centre platforms where predictable latency and sustained IOPS matter more than burst performance. As a single-port 2.5in SAS device, the 0B25168 integrates cleanly into SAS back-end topologies and standard RAID controllers, supporting consistent queue handling for multi-tenant storage tiers.

Built on CMR recording with 64MB cache, the 0B25168 is tuned for transactional write patterns and rebuild behaviour in RAID groups, helping maintain steady performance under mixed read/write pressure. The 10K spindle speed positions the 0B25168 for virtualization and database log/data volumes where access locality and response-time control are essential, while its power profile (6.7W active, 3.7W idle) supports thermal planning in high-density disk shelves and 2U storage nodes.

Why Choose the 0B25168?

The 0B25168 delivers a balanced density-to-performance profile for enterprises standardising on 2.5in SAS tiers to maximise bays per rack unit without sacrificing serviceability. Designed for continuous operation, the 0B25168 supports scalable deployments from single servers to shared arrays, enabling consistent lifecycle planning across RAID sets, spares strategy, and capacity expansion.

WD designs Ultrastar enterprise HDDs with a reliability-first engineering approach, focusing on controlled acoustics, thermal tolerance, and sustained duty-cycle operation aligned to modern data centre qualification processes and storage-array interoperability requirements.

Key Applications:

• Transactional database storage
• Virtualization storage tiers
• SAS back-end disk shelves
