About the WD Ultrastar DC HC570 22TB Enterprise HDD
The WD Ultrastar DC HC570 22TB (part number WD-HC570-22TB) consumes just 5.0W at idle and 7.4W during active read/write operations—critical efficiency metrics for power-dense JBOD and data center environments where thousands of drives run simultaneously. This Western Digital enterprise-class HDD delivers 22TB formatted capacity in a standard 3.5-inch form factor, combining helium-sealed construction with CMR recording technology to maximize reliability across demanding 24/7 workloads.
Built for storage architects managing petabyte-scale infrastructure, the HC570 series balances capacity with thermal efficiency. Its 512MB cache, 7200 RPM spindle speed, and 2.5M-hour MTBF support up to 550TB annualized workload rates, while rotational vibration compensation (RVPE) minimizes performance degradation in multi-drive arrays. The SATA 6Gb/s interface integrates seamlessly into legacy and modern storage systems alike. Western Digital specifies wide temperature tolerances (0–60°C operating) and robust shock protection, ensuring reliability across diverse facility conditions.

Typical Enterprise Deployment Scenarios
- Large-scale cold storage and archival repositories requiring low idle power consumption and high sequential throughput
- Multi-petabyte JBOD expansions in hyperscale data centers where per-drive power efficiency directly reduces operational costs
- Video surveillance and media asset management systems with sustained high workload rates and 24/7 operational cycles
- Backup and disaster recovery infrastructure demanding reliable long-term retention without frequent access patterns
- Content distribution networks and streaming platforms needing dense, power-efficient capacity at the edge
