0F22798 WD Ultrastar 7K6000 2TB SAS 128 MB 3.5" Server HDD

Enterprise 3.5in SAS HDD for 24/7 RAID and Tiered Storage featuring 4Kn CMR with the 0F22798

The 0F22798 is a WD Ultrastar 7K6000 3.5in internal enterprise HDD designed for predictable performance and sustained throughput in server and storage enclosures. Using a 7200RPM CMR media design with 128MB cache, it supports consistent write behavior that aligns with RAID rebuild windows and mixed read/write data centre tiers without the latency variability associated with shingled recording.

For platform integration, the 0F22798 connects via single-port SAS and uses a 4Kn sector format to optimize modern file systems and reduce write amplification in environments standardized on 4KB blocks. The 2TB capacity targets performance-oriented capacity pools, log volumes, and application datasets where SAS backplanes, expanders, and enterprise HBA controllers are already the architectural baseline. With a 2.0M-hour MTBF rating and 24/7 duty-cycle design, the drive is suited to dense storage shelves where thermal stability and consistent error recovery behavior are critical for array health.

Why Choose the 0F22798?

The 0F22798 is engineered for reliable scale-out deployment in enterprise RAID arrays, delivering a balanced density-to-performance profile for SAS infrastructures that prioritize predictable serviceability. It supports operational continuity in always-on environments while maintaining a clear upgrade path across homogeneous drive sets, simplifying spares strategy and capacity planning in standardized data centre storage tiers.

WD’s Ultrastar engineering emphasizes controlled firmware behavior, robust mechanical design, and qualification for multi-drive enclosures, aligning with modern data centre expectations for uptime, interoperability, and lifecycle management. The 0F22798 also supports Instant Secure Erase (ISE) to streamline compliance-oriented decommissioning workflows.

Key Applications:

• Enterprise RAID arrays
• SAS storage shelves and JBODs
• Tiered data centre HDD pools
• Log and index volumes
• Compliance-driven secure decommissioning
