0F27504 HGST WD Ultrastar DC HC510 10TB SATA 256 MB 3.5" Server HDD

Capacity-Optimised 3.5" Datacenter SATA HDD featuring helium-sealed CMR design with the 0F27504

The 0F27504 is a 10TB 3.5" internal enterprise HDD engineered for capacity-optimised storage nodes and nearline tiers where predictable throughput, consistent latency, and controlled power are required across large drive counts. As a SATA device for standard server and JBOD backplanes, the 0F27504 integrates cleanly into x86 storage platforms, HBA/RAID architectures, and scale-out clusters without forcing changes to the CPU or PCIe topology.

Built on a 7200 RPM CMR recording profile with 256MB cache, the 0F27504 targets sustained sequential performance and stable rebuild behaviour compared with SMR approaches, supporting operational continuity in dense arrays. The 4Kn sector format aligns with modern OS and storage stacks to reduce translation overhead and improve integrity in capacity tiers. A helium-filled mechanical design improves areal density and efficiency, while Power Disable support enables secure remote power cycling in serviceable backplanes. Secure Erase (SE) assists with compliant decommissioning workflows, and the 24x7 duty cycle with 2.5M hours MTBF positions the 0F27504 for long-lived, always-on environments.

Why Choose the 0F27504?

The 0F27504 delivers a practical density-to-power profile for datacenter fleets, allowing higher usable capacity per rack unit while maintaining enterprise serviceability expectations. The architecture is optimised for scalable deployment in homogeneous drive populations, supporting predictable operations in storage nodes, backup targets, and object stores where reliability and consistent behaviour matter more than peak IOPS.

HGST engineering focuses on datacenter-class validation, endurance under continuous duty, and compatibility with modern server storage standards, resulting in a drive platform built for controlled thermals, predictable performance, and operational reliability at scale.

Key Applications:

• Capacity-optimised storage nodes
• Backup and archive repositories
• Nearline storage tiers
• Scale-out object storage
• Distributed file systems
