WUH721414ALE6L4 WD Ultrastar DC HC530 14TB SATA 512 MB 3.5" Server HDD

High-Performance 3.5in Datacenter SATA HDD featuring helium-sealed CMR capacity with the WUH721414ALE6L4

The WUH721414ALE6L4 is a 14TB 3.5in enterprise HDD designed for 24x7 datacenter duty cycles where predictable throughput and consistent latency matter more than burst performance. In RAID shelves and dense storage nodes, the CMR recording method supports stable write behavior for rebuilds and sustained ingest, while a 7200RPM spindle and 512MB cache help maintain queue depth efficiency under mixed reads and sequential writes.

Built for modern server platforms, the WUH721414ALE6L4 integrates cleanly into SATA backplanes behind current HBA and RAID controller architectures, scaling across PCIe-attached storage controllers and JBOD expansion domains without changing the operational model. 4Kn media with 512e emulation simplifies alignment across operating systems and hypervisors, making the drive suitable for capacity tiers in software-defined storage, nearline object storage, and backup repositories where integrity and lifecycle management are primary design goals.

Why Choose the WUH721414ALE6L4?

The WUH721414ALE6L4 delivers high capacity per bay to optimize rack-level density while maintaining enterprise reliability targets, including 2.5M hours MTBF. This supports predictable scaling in capacity tiers, reduces the number of spindles required for a given footprint, and aligns with standardized service procedures in multi-node deployments and storage arrays.

WD engineers the Ultrastar platform for consistent operation in vibration-aware enclosures, emphasizing firmware behavior, endurance characteristics, and qualification processes that map to modern data center standards. The WUH721414ALE6L4 also includes Secure Erase support for controlled decommissioning workflows and governance requirements.

Key Applications:

• Capacity-tier HDD storage arrays
• Software-defined storage
• Server RAID pools
• Backup and archive repositories
• Nearline object storage
