0F48051 WD Ultrastar DC HC570 22TB SAS 512 MB 3.5" Server HDD

High-Density 3.5-inch SAS Enterprise HDD engineered for secure capacity tiers with the 0F48051

The 0F48051 is a 22TB 3.5-inch SAS hard drive designed for data center capacity layers where predictable throughput, sustained write behavior, and encryption at rest are mandatory. Built on CMR recording with EAMR assist, it supports consistent performance for bulk data streams and rebuild scenarios, while maintaining enterprise-class reliability targets for 24x7 duty cycles.

For platform integration, the 0F48051 aligns with modern server and storage backplanes that prioritize SAS connectivity, high drive counts, and controlled latency under mixed workloads. A 512MB cache combined with OptiNAND and ArmorCache write-cache data protection helps preserve in-flight metadata and cache data during power events, improving array resiliency. The 4Kn sector format with 512e emulation enables cleaner alignment for contemporary filesystems and object storage stacks while preserving compatibility with legacy environments, making the 0F48051 a pragmatic choice for phased migrations.

Why Choose the 0F48051?

The 0F48051 delivers a strong density-to-bay ratio for capacity tiers in servers and storage arrays, reducing rack footprint and controller overhead per usable terabyte. Its Self-Encrypting Drive (SED) hardware encryption supports secure multi-tenant operations and compliance-driven deployments without external key handling overhead, and the 0F48051 scales cleanly from single-node archival to large SAS shelves supporting object and backup repositories.

WD designs Ultrastar data center drives around disciplined validation, predictable thermal/power envelopes, and firmware behaviors optimized for enterprise error recovery and array interoperability. This engineering focus aligns with OCP 2.0 initiatives and modern data center standards that require measurable reliability, serviceability, and consistent fleet behavior.

Key Applications:

• High-density capacity tiers for servers and storage arrays
• Backup and archival repositories
• Object storage nodes
• Bulk data lakes and content libraries
• Encrypted data-at-rest environments
