0F22956 WD Ultrastar 7K6000 4TB SAS 128 MB 3.5" Server HDD

High-Density 3.5in SAS Enterprise HDD for Capacity-Tier Storage with the 0F22956

The 0F22956 is a 3.5in internal WD Ultrastar 7K6000 SAS hard drive engineered for capacity-tier server storage in SAS backplanes, JBOD enclosures, and RAID shelves where predictable latency and sustained throughput matter more than peak IOPS.

Designed around CMR recording and a 7200 RPM mechanical platform, the 0F22956 supports consistent write behaviour under rebuild and scrub operations, helping storage controllers maintain stable performance in mixed read/write duty cycles. Its SAS interface integrates cleanly into dual-path enterprise topologies and expands effectively in scale-out shelves, while the 512n sector format simplifies legacy alignment in heterogeneous fleets. With 4TB capacity and on-drive cache, the 0F22956 targets dense datasets such as log retention, backup repositories, and content stores, optimised for 24x7 operation and serviceability in standard hot-swap bays.

Why Choose the 0F22956?

The 0F22956 delivers a balanced density-to-performance profile for organisations building cost-efficient tiers behind SAS HBAs and RAID controllers, while maintaining enterprise reliability and operational continuity across large drive counts. The 0F22956 also strengthens compliance-oriented deployments by combining capacity scaling with hardware-based security and predictable behaviour during maintenance windows.

WD’s Ultrastar engineering emphasises long-life components, conservative firmware tuning, and qualification for modern data centre standards, aligning the 0F22956 with continuous duty cycles and structured lifecycle management. With SED capability and TCG Enterprise SSC support, the 0F22956 enables hardware encryption that integrates with enterprise key management workflows without relying on host CPU resources.

Key Applications:

• JBOD and RAID capacity tiers
• Backup and recovery repositories
• Log retention and audit archives
• Virtualisation and private cloud storage pools
• Media and content repositories
