0F38460 WD Ultrastar DC HC550 16TB SATA 512 MB 3.5" Server HDD

High-Capacity 3.5-inch Enterprise SATA HDD for Datacenter Arrays with the 0F38460

The 0F38460 is a WD Ultrastar DC HC550 16TB enterprise HDD engineered for 24x7 datacenter duty cycles in rack servers, JBOD shelves, and capacity-optimised storage arrays. As a 3.5-inch internal SATA drive, it targets predictable bulk throughput and efficient capacity scaling where high IOPS are not the primary constraint, enabling architects to balance performance per watt against rack-level density.

Designed for modern server and storage backplanes, the 0F38460 supports 512e and 4Kn emulation to align with mixed sector-size environments and easing migration planning. A 7200 RPM spindle and 512MB cache, combined with EAMR and TDMR recording technologies, help sustain steady sequential transfer behaviour across large volumes, supporting backup windows, archive ingest, and general-purpose file or object tiers. The 0F38460 also integrates self-encrypting drive capabilities for media-level protection within enterprise security models.

Why Choose the 0F38460?

The 0F38460 delivers a pragmatic density-to-reliability profile for capacity layers that must scale without increasing operational risk. With a 2.5M-hour MTBF target and a power profile suited to always-on arrays, the 0F38460 supports consistent fleet behaviour, simplifying spares strategy, lifecycle planning, and expansion within SATA-based platforms.

WD builds Ultrastar-class drives around disciplined validation, predictable firmware behaviour, and compatibility with standard enterprise storage topologies. This engineering approach aligns the 0F38460 with common datacenter requirements for long service life, controlled acoustics and thermals, and integration into monitored, policy-driven storage environments.

Key Applications:

• Bulk storage tiers in rack servers
• Backup and recovery repositories
• Archive and cold data platforms
• Capacity-focused RAID arrays and JBOD shelves
• General-purpose server storage pools
