0F27507 WD Ultrastar DC HC510 8TB SATA 256 MB 3.5" Server HDD

High-Density 3.5in Datacenter HDD for Nearline Storage Architectures with the 0F27507

The 0F27507 is a WD Ultrastar DC HC510 8TB internal 3.5in datacenter HDD engineered for scale-out storage nodes and RAID arrays where predictable latency and sustained throughput are required. Built on a helium-sealed mechanical platform, the 0F27507 targets high capacity per bay while maintaining stable thermals and power behavior in dense server chassis.

Using a SATA interface and a 7200RPM spindle with 256MB cache, the 0F27507 integrates cleanly into common HBA and backplane designs for nearline tiers and cold-data pools. Its CMR recording format supports consistent write performance under mixed workloads compared to SMR approaches, while the 4Kn native sector format aligns with modern filesystems and object storage stacks optimized for 4KB I/O. For data center serviceability, the 0F27507 supports Power Disable (PWDIS) for remote power-cycle control and Secure Erase (SE) for streamlined decommissioning workflows.

Why Choose the 0F27507?

The 0F27507 delivers an enterprise-appropriate balance of capacity density and operational stability for always-on storage, making it a strong fit for expanding RAID groups, scale-out nodes, and repository tiers without changing platform design. With a 2.5M hours MTBF rating and 24/7 duty expectations, the 0F27507 supports predictable lifecycle planning and consistent fleet behavior across large deployments.

WD designs Ultrastar datacenter HDDs around validated firmware control, vibration-aware mechanics, and reliability engineering aligned with modern rack-level power and thermal constraints, enabling repeatable integration into standardized storage architectures.

Key Applications:

• 24/7 RAID arrays
• Scale-out storage nodes
