0F48154 WD Ultrastar DC HC570 22TB SATA 512 MB 3.5" Server HDD

High-Capacity 3.5in Datacenter SATA HDD for Nearline Fleets with the 0F48154

The 0F48154 is a 22TB WD Ultrastar DC HC570 internal datacenter HDD engineered for high-density, capacity-oriented tiers where cost-per-TB and predictable latency matter. Built on 7200RPM CMR media with EAMR, it supports sustained sequential throughput and stable write behavior, making it suitable for RAID groups and scale-out storage nodes that must maintain consistent rebuild and scrub performance.

With a SATA interface optimized for broad server and JBOD compatibility, the 0F48154 integrates cleanly into 512e and 4K sector environments to simplify migration while preserving alignment for modern filesystems. A 512MB cache helps absorb bursts and smooth queue depth variability, while the platform is designed for 24x7 duty cycles in multi-drive chassis. For security-sensitive retention workflows, the 0F48154 adds SED hardware encryption and Sanitize Crypto Erase to support rapid decommissioning and policy-driven data lifecycle controls without software overhead.

Why Choose the 0F48154?

The 0F48154 delivers a balanced density-to-power profile for bulk and nearline tiers, enabling higher usable capacity per rack unit while keeping operational characteristics consistent across large drive fleets. Its enterprise reliability model and long service-life design simplify standardization, allowing IT teams to scale capacity in predictable increments across NAS/SAN shelves and object storage nodes.

WD designs Ultrastar datacenter drives around sustained workload operation, deterministic firmware behavior, and platform validation for modern server and storage backplanes. The result is a deployment-friendly component aligned with enterprise standards for continuous operation, security governance, and lifecycle management at scale.

Key Applications:

• Scale-out object and file storage nodes
• RAID arrays and JBOD expansion shelves
• Backup, archival, and nearline tiers
• Cold-to-warm dataset repositories
• Compliance-driven retention storage
