0F27357 WD Ultrastar DC HC510 8TB SAS 256 MB 3.5" Server HDD

High-Density 3.5-inch Enterprise SAS HDD for bulk storage and RAID tiers with the 0F27357

The 0F27357 is a WD Ultrastar DC HC510 8TB internal 3.5-inch enterprise HDD designed for 24x7 data centre server and storage deployments where predictable throughput, controlled latency, and consistent rebuild behaviour matter. Using 12Gb/s SAS, the 0F27357 integrates cleanly into dual-ported enterprise backplanes and RAID controllers, supporting scalable drive counts while maintaining deterministic link performance under sustained queue depths.

Built on a 7200 RPM CMR recording architecture with 256MB cache, the 0F27357 is optimised for bulk storage and backup tiers that prioritise sequential efficiency and stable write characteristics over burst-only performance. The 4Kn sector format with 512e emulation helps align with modern OS and hypervisor stacks while preserving compatibility in mixed environments, and its helium-filled mechanics improve power efficiency and thermal behaviour in dense enclosures, reducing operational friction in high-bay racks.

Why Choose the 0F27357?

For capacity-led platforms, the 0F27357 delivers an effective density-to-reliability profile for RAID arrays, archive repositories, and scale-out storage nodes. The 0F27357 supports enterprise operational expectations through sustained duty-cycle design, predictable error recovery characteristics for controller-managed arrays, and a deployment model that scales from small shelves to multi-chassis SAS domains without changing media type.

WD engineers the Ultrastar family for data centre endurance, focusing on consistent performance under continuous workloads, tight mechanical tolerances, and firmware behaviour aligned with enterprise storage standards. The 0F27357 also adds Self-Encrypting Drive capability with hardware-based encryption to support security baselines without introducing host CPU overhead.

Key Applications:

• Data centre bulk storage
• RAID arrays and JBOD shelves
• Backup and archive tiers
• Log retention and compliance storage
