0F27408 WD Ultrastar DC HC510 8TB SAS 256 MB 3.5" Server HDD

High-Density 3.5-inch Datacenter SAS HDD for nearline capacity tiers with the 0F27408

The 0F27408 is a WD Ultrastar DC HC510 8TB helium-filled 3.5-inch internal HDD engineered for enterprise servers and storage arrays that need predictable bulk capacity on SAS backplanes. Designed for 24/7 operation, it aligns with modern CPU and RAID controller platforms by delivering consistent rotational performance for sequential and mixed read/write profiles typical of backup, archive, and nearline tiers.

With a single-port SAS interface and 4Kn sector format, the 0F27408 integrates cleanly into contemporary storage architectures that prioritize end-to-end 4K alignment, reducing write amplification and improving RAID rebuild efficiency in large pools. CMR recording supports stable latency under sustained workloads, while the on-drive cache complements controller-side caching and queue management. The helium design enables higher areal efficiency and lower power draw per TB, improving chassis thermals and allowing denser deployments without sacrificing serviceability.

Why Choose the 0F27408?

The 0F27408 provides an enterprise-appropriate density-to-reliability profile for SAS HDD tiers where cost-per-TB and operational predictability drive architecture decisions. It scales effectively from small RAID groups to multi-shelf pools, supports continuous duty cycles, and is well suited for standardized fleet deployments where consistent firmware behavior and controlled error recovery are essential for array stability.

WD designs Ultrastar datacenter drives around sustained availability, qualification discipline, and tight integration with common server and storage standards. The 0F27408 reflects that approach with datacenter-class mechanics, secure erase capability for lifecycle control, and reliability characteristics intended for long-lived infrastructure.

Key Applications:

• Backup repositories
• Nearline SAN/NAS capacity tiers
• RAID bulk storage pools
