0F27405 WD Ultrastar DC HC510 10TB SAS 256 MB 3.5" Server HDD

High-Density 3.5in Datacenter SAS HDD designed for RAID and compliant storage with the 0F27405

The 0F27405 is a WD Ultrastar DC HC510 10TB datacenter hard drive engineered for enterprise SAS storage tiers where predictable latency, sustained throughput, and serviceable capacity matter more than short-burst performance. Built for 24x7 duty cycles, the 0F27405 integrates a helium-filled mechanical platform to reduce turbulence and power draw, supporting dense JBOD expansion shelves and large RAID groups without compromising enclosure thermals.

Architecturally, the 0F27405 aligns with SAS backplanes and dual-ported enterprise controllers for high-availability designs. CMR recording supports consistent write behavior under parity workloads, while 4Kn native sectors improve efficiency in modern filesystems and storage stacks that are optimized for 4KB alignment. With 256MB cache, the 0F27405 helps smooth command queues during mixed read/write streams typical of backup repositories and capacity-focused virtualization datastores.

Why Choose the 0F27405?

The 0F27405 provides a balanced density-to-reliability profile for capacity tiers that must scale predictably across racks and enclosures. It is well suited to standardized SAS infrastructures where operational consistency, hot-swap serviceability, and controller-managed resilience are primary deployment drivers, enabling straightforward growth from initial RAID sets to multi-shelf pools.

WD designs Ultrastar platforms around datacenter qualification, long-life mechanical stability, and enterprise firmware behavior to meet modern storage enclosure, RAID, and JBOD interoperability requirements. The 0F27405 also supports self-encrypting drive capability using TCG Enterprise SSC with FIPS 140-2 Level 2, enabling secure retirement and compliance-aligned data handling.

Key Applications:

• SAS RAID arrays for capacity tiers
• JBOD expansion shelves
• Private cloud bulk storage
• Virtualization backup repositories
• Compliance-focused encrypted storage
