WD221KFGX
High-Capacity 3.5in SATA NAS HDD featuring CMR reliability with the WD221KFGX
The WD221KFGX is a 22TB 3.5in internal enterprise HDD engineered for RAID-based NAS platforms where predictable write behavior and sustained throughput matter more than peak IOPS. Built on CMR recording and tuned for 24x7 duty cycles, the WD221KFGX supports consistent rebuild performance and minimizes array risk under mixed file services and backup workloads.
In modern NAS architectures, CPU generation, DRAM, and PCIe lanes mainly determine network and cache acceleration, while the storage tier must deliver stable latency under vibration and concurrent streams. The WD221KFGX integrates SATA connectivity with 4Kn/512e sector support for broad controller compatibility, plus NASware 3.0 features such as ERC and NCQ to reduce timeout-driven dropouts in RAID. A 7200 RPM spindle and 512MB cache help keep large sequential transfers efficient, while OptiNAND and multi-axis sensing improve behavior in multi-bay enclosures where mechanical coupling can otherwise degrade performance.
Why Choose the WD221KFGX?
The WD221KFGX is positioned for density-focused NAS shelves that must scale capacity without compromising array stability. With 2.5M hours MTBF, vibration balance technology, and RAID-oriented error recovery control, the WD221KFGX supports predictable operations in SMB and scale-out NAS deployments, simplifying growth planning and lifecycle management across multiple nodes.
WD designs this class of drive around data centre-aligned reliability engineering, emphasizing continuous operation, controlled error handling, and enclosure-aware mechanics. The result is an HDD profile that fits common NAS standards and maintains consistency under sustained multi-user access patterns.
Key Applications:
- SMB NAS arrays
- Scale-out NAS capacity nodes
- RAID file services and shared storage
- Backup targets and archive tiers
- Bulk capacity for media and datasets
At Happyware - Server Hardware you benefit from non-binding offers tailored to your NAS capacity plan for WD221KFGX rollouts, and bulk order discount options that align with multi-bay refresh cycles and phased expansions.
