0F27358 WD Ultrastar DC HC510 8TB SAS 256 MB 3.5" Server HDD

High-Capacity 3.5in Enterprise SAS Datacenter HDD engineered for 24/7 arrays with the 0F27358

The 0F27358 is an internal WD Ultrastar DC HC510 8TB 3.5in SAS HDD designed for enterprise storage tiers where predictable latency and sustained throughput matter more than burst performance. Built on a 7200RPM platform with CMR recording, it delivers consistent write behavior for RAID rebuilds and mixed I/O patterns common in SAN/NAS shelves and dense JBOD enclosures.

With a SAS interface for dual-port, multi-initiator paths, the 0F27358 aligns with resilient storage fabrics and backplanes typically deployed behind RAID controllers or HBA-based software-defined storage. The 512e/4Kn sector format supports modern alignment practices, while the 256MB cache helps stabilize small-block transaction handling without compromising sequential streaming efficiency. Secure Erase (SE) supports lifecycle processes for decommissioning and redeployment, and the 2.5M-hour MTBF targets high availability in 24/7 duty cycles with controlled power profiles for steady-state racks.

Why Choose the 0F27358?

The 0F27358 provides a balanced density-to-performance profile for capacity tiers, enabling predictable scaling by adding spindles and shelves rather than redesigning the storage layer. It fits enterprise reliability requirements for continuous operation, supports straightforward integration into existing SAS topologies, and offers an efficient path to expand bulk capacity while keeping operational procedures consistent across fleets.

WD engineers Ultrastar datacenter drives with a focus on sustained workload integrity, rigorous qualification, and compatibility with modern rack and enclosure standards. This approach supports dependable operation in shared storage environments where firmware behavior, error recovery characteristics, and long service life are decisive.

Key Applications:

• RAID arrays and JBOD capacity expansion
• SAN/NAS shelves for mixed workloads
• Backup repositories and archive pools
• Capacity tiers for software-defined storage
