0F27402 WD Ultrastar DC HC510 10TB SAS 256 MB 3.5" Server HDD

High-Density 3.5in Enterprise SAS HDD for 24x7 Datacenter Storage with the 0F27402

The 0F27402 is a WD Ultrastar DC HC510 10TB 3.5in SAS hard drive engineered for capacity-oriented primary storage in RAID arrays, SAN/NAS expansion, and scale-out storage servers. Designed for continuous duty cycles, the 0F27402 targets predictable throughput and consistent write behavior in shared storage environments where rebuild windows, sequential ingest, and sustained write streams matter.

Architecturally, the 0F27402 aligns with enterprise SAS backplanes and storage controllers for dual-ported, high-availability designs while maintaining cost-effective capacity per rack unit. CMR recording supports stable performance under mixed workloads and during RAID parity operations. The 4Kn (4KB native) sector format improves format efficiency and integrity for modern filesystems and object stores, while the 256MB cache and 7200 RPM spindle speed help smooth I/O bursts in tiering and backup repositories. A helium-filled design contributes to lower power draw and thermal load, enabling denser shelves without compromising airflow planning.

Why Choose the 0F27402?

The 0F27402 provides a balanced density-to-reliability profile for enterprise storage tiers that prioritize capacity, deterministic behavior, and serviceability. With datacenter-class endurance and a 2.5M-hour MTBF rating, the 0F27402 supports scalable deployments across large RAID sets and multi-shelf expansions, helping standardize drive qualification and lifecycle management across fleets.

WD designs Ultrastar platforms around controlled vibration behavior, workload consistency, and long-term operational stability for modern datacenters. The 0F27402 also supports Instant Secure Erase (ISE) to simplify secure decommissioning workflows and align with operational security processes.

Key Applications:

• RAID arrays for primary capacity storage
• SAN/NAS expansion shelves
• Scale-out storage servers
• Backup repositories and archive tiers
• Capacity-centric tiering pools
