0B26312 WD Ultrastar 7K3000 2TB SAS 64 MB 3.5" Server HDD

Capacity-Dense 3.5in Enterprise SAS HDD for 24/7 Nearline Storage with the 0B26312

The 0B26312 is a WD Ultrastar 7K3000 3.5in internal enterprise HDD designed for capacity-oriented SAS tiers in rack servers and external arrays where predictable latency and sustained duty cycles matter. Positioned for nearline and active archive roles, the 0B26312 supports always-on operation in multi-drive enclosures, aligning with enterprise RAID groups and storage nodes that prioritize availability and controlled rebuild behavior.

Built on a CMR recording architecture, the 0B26312 provides consistent write characteristics that integrate cleanly with controller caches, snapshot schedules, and background scrubbing. The SAS interface enables deterministic command handling and dual-path friendly topologies at the system level, while the onboard 64MB cache helps smooth small-block bursts typical of metadata, logging, and mixed read/write streams. In dense chassis designs, the 0B26312 is a practical building block for scaling bulk capacity without shifting workloads to higher-cost flash, keeping PCIe lanes and NVMe bays reserved for performance tiers.

Why Choose the 0B26312?

The 0B26312 is optimized for a high density-to-performance balance in enterprise storage pools, offering capacity scaling that remains operationally stable under continuous utilization. Deployed as an active archive or nearline tier, the 0B26312 supports predictable fleet behavior for monitoring, failure domain planning, and service windows, making it well suited to standardized server and array rollouts where repeatability is critical.

WD designs Ultrastar-class drives with an engineering focus on sustained workload operation, qualification discipline, and compatibility across common SAS backplanes and RAID/HBA ecosystems. The 0B26312 aligns with modern data center requirements for managed lifecycle, consistent performance under load, and dependable bulk storage economics in shared infrastructure.

Key Applications:

• SAS nearline storage tiers in servers and arrays
• Active archive and compliance retention repositories
• Backup-to-disk and disk-based VTL capacity pools
• Virtualization and private cloud bulk datastores
