About the WD Red Pro 22TB NAS Hard Drive
SATA 6Gb/s interface, 3.5-inch form factor — the WD Red Pro 22TB NAS Hard Drive (part number WD221KFGX) is purpose-built for high-capacity network storage environments demanding reliability and sustained performance. Manufactured by Western Digital, this enterprise-class drive delivers 272 MB/s maximum sustained transfer rate and operates at 7200 RPM, making it ideal for storage architects and IT procurement teams deploying multi-bay NAS systems that require both capacity and speed.
The WD Red Pro 22TB combines Western Digital's NASware firmware technology with Rotational Vibration sensors to minimize performance degradation in multi-drive environments. With a 512 MB cache and workload rating of 550 TB/year, this drive is engineered to handle continuous RAID operations across configurations including RAID 0, 1, 5, 6, and 10. The drive supports up to 24-bay NAS systems, delivering 600,000 load/unload cycles and operating efficiently across 0°C to 65°C temperature ranges. Power consumption remains modest at 9.2 W during read/write operations and just 1.1 W in standby mode, helping reduce operational costs in large-scale deployments.
Typical Enterprise Deployment Scenarios
- Multi-bay NAS storage clusters in data centers requiring high-capacity single drives for 16–24 bay configurations
- RAID 6 and RAID 10 implementations for financial services, healthcare, and media companies needing redundancy with sustained throughput
- Continuous backup and archival systems benefiting from the 550 TB/year workload rating and CMR recording technology
- Virtualization host storage supporting mixed read/write workloads with minimal vibration-induced latency
- Remote office and branch office (ROBO) storage nodes requiring reliable, space-efficient capacity in compact form factors
