WUH722222AL5204 WD Ultrastar DC HC570 22TB SAS 512 MB 3.5" Server HDD

High-Density 3.5-inch SAS Datacenter HDD featuring helium-sealed CMR capacity with the WUH722222AL5204

The WUH722222AL5204 is a datacenter-class 3.5-inch SAS hard drive designed to deliver predictable bulk capacity in enterprise server and storage platforms where throughput consistency and serviceability matter more than peak IOPS. As a WD Ultrastar DC HC570 lineage device, it fits naturally behind SAS expanders, in dual-port storage backplanes, and across JBOD shelves that require deterministic behavior under sustained write and rebuild activity.

Architecturally, WUH722222AL5204 supports scalable storage tiers for SAN/NAS and software-defined storage by combining CMR media with a 7,200RPM spindle and large cache to stabilize sequential throughput and reduce variability during mixed workloads. The 4Kn native format with 512e emulation simplifies integration across modern operating systems and controllers while preserving alignment options for capacity pools. Power Disable support enables controlled remote power cycling in dense enclosures, and Secure Erase assists operational data sanitization workflows across decommissioning and redeployments.

Why Choose the WUH722222AL5204?

The WUH722222AL5204 provides a practical density-to-reliability profile for enterprises standardizing on SAS for shared backplanes and multi-initiator environments, reducing drive counts per shelf while keeping management consistent. With a 24x7 duty cycle design and high MTBF targets, WUH722222AL5204 supports scale-out capacity growth in backup, archival, and nearline tiers where long service life and predictable rebuild behavior are key to operational risk control.

WD engineers Ultrastar platforms with a focus on datacenter interoperability, sustained workload operation, and field-proven reliability characteristics aligned to modern rack, JBOD, and SDS reference architectures. The helium-filled mechanical design of WUH722222AL5204 is optimized for thermals and vibration behavior in dense deployments, supporting consistent operation in controlled data centre environments.

Key Applications:

• SAS JBOD capacity expansion
• SAN/NAS nearline storage tiers
• Backup repositories
• Archive and retention pools
• Software-defined storage clusters
