0F27356 WD Ultrastar DC HC510 8TB SAS 256 MB 3.5" Server HDD

High-Density 3.5in Datacenter SAS HDD for 24/7 Storage Arrays with the 0F27356

The 0F27356 is a WD Ultrastar DC HC510 8TB internal datacenter hard drive engineered for predictable throughput and sustained availability in server and storage platforms. Designed to integrate cleanly into modern CPU and HBA/RAID architectures, it leverages a 12Gb/s SAS interface to maintain consistent link performance in shared backplanes and multi-bay enclosures where queue depth and path redundancy matter.

For memory and I/O balancing, the 0F27356 supports mixed sequential and random access patterns typical of bulk tiers behind cache-rich controllers, with 256MB cache and CMR recording to preserve write consistency under rebuild and background scan activity. A 7200RPM spindle and helium-filled design improve steady-state latency and power efficiency, while 4Kn formatting with 512e emulation simplifies deployment across legacy and modern OS stacks. This makes the 0F27356 well aligned for JBOD expansion shelves, scale-out storage nodes, and backup targets where PCIe lanes are reserved for networking and accelerators rather than NVMe-only capacity.

Why Choose the 0F27356?

The 0F27356 delivers a strong density-to-reliability profile for enterprise fleets that prioritise uptime, serviceability, and predictable performance per rack unit. With 24x7 duty design and 2.5M hours MTBF, the 0F27356 supports scalable growth in storage arrays while keeping operational risk and maintenance windows under control.

WD engineers Ultrastar platforms for datacenter qualification discipline, consistent firmware behaviour, and long-life component selection aligned with standardised SAS infrastructures. The 0F27356 also includes Instant Secure Erase (ISE) to support controlled decommissioning workflows without introducing self-encryption dependencies.

Key Applications:

• Datacenter storage arrays and JBODs
• Server bulk storage tiers
• Backup and archive repositories
• 24/7 mixed I/O virtualisation storage
• Capacity expansion for scale-out storage
