0F27407 WD Ultrastar DC HC510 8TB SAS 256 MB 3.5" Server HDD

High-Density 3.5in Enterprise SAS HDD platform optimized for secure 24/7 capacity with the 0F27407

The 0F27407 is a WD Ultrastar DC HC510 8TB 3.5in enterprise HDD designed for nearline capacity tiers where predictable latency, long duty cycles, and data-at-rest protection are mandatory. The 0F27407 integrates a 7200RPM CMR media design with a SAS interface for server and array backplanes, aligning with modern storage controllers and expander topologies that prioritize deterministic behavior under sustained queue depth.

Architecturally, the 0F27407 targets capacity-per-rack efficiency without sacrificing integrity controls. The 4Kn native sector format reduces write amplification and improves alignment in properly configured filesystems and object stores, while 256MB cache supports burst handling during rebuilds and snapshot-heavy operations. For expansion planning, the SAS attachment model keeps the 0F27407 well suited to dense JBOD shelves and scale-out nodes, enabling consistent drive handling, enclosure management, and multi-bay serviceability across large pools. Hardware-based self-encryption helps meet security baselines with minimal host CPU overhead.

Why Choose the 0F27407?

The 0F27407 delivers a balanced density-to-performance profile for enterprise capacity tiers by combining helium-enabled mechanics, 24/7 duty-cycle design, and SAS operational consistency. In large deployments, the 0F27407 supports scalable pool growth with predictable fleet behavior, helping architects standardize secure bulk storage while maintaining service windows, rebuild planning, and platform reliability targets.

WD engineers this class of Ultrastar drives around datacenter endurance and operational discipline, emphasizing validated firmware behavior, sustained thermal characteristics, and long-life mechanical design aligned with modern rack, chassis, and enclosure standards.

Key Applications:

• Data center storage arrays and JBOD shelves
• Enterprise backup and archive repositories
• Software-defined storage capacity pools
• Secure nearline tiers with encryption requirements
