WUH721414AL5204 WD Ultrastar DC HC530 14TB SAS 512 MB 3.5" Server HDD

High-Performance 3.5-inch Enterprise Datacenter HDD featuring 12Gb/s SAS throughput with the WUH721414AL5204

WUH721414AL5204 is a WD Ultrastar DC HC530 14TB internal HDD engineered for dense storage tiers where predictable latency, sustained sequential throughput, and continuous duty cycles matter more than compute acceleration. In modern CPU-based storage servers and scale-out nodes, the drive aligns with RAID controllers and SAS HBAs to deliver consistent behavior under multi-stream workloads typical of backup windows and object storage ingestion.

Designed for SAS 12Gb/s backplanes, WUH721414AL5204 integrates cleanly into PCIe-based storage architectures where the expansion domain is built around HBA/RAID cards rather than NVMe lanes. CMR recording supports stable rebuild characteristics and write amplification control in parity RAID, while 4Kn/512e flexibility simplifies platform standardization across legacy and next-generation sector formats. A 7200RPM design with 512MB cache targets mixed queue depths in JBOD and shared-nothing storage, optimizing capacity per rack unit without sacrificing operational consistency.

Why Choose the WUH721414AL5204?

WUH721414AL5204 provides an enterprise-appropriate density-to-performance balance for bulk tiers, enabling predictable scaling of arrays and enclosures without introducing flash-specific procurement and lifecycle complexity. Its reliability profile supports always-on deployment logic, helping storage engineers maintain service-level stability during sustained ingest, scrub, and rebuild operations across large drive counts.

WD designs the Ultrastar platform with datacenter qualification, consistent firmware behavior, and serviceability in mind, aligning with modern rack-scale standards for hot-swap bays, SAS expanders, and secure decommissioning practices. Features such as Secure Erase and a 2.5M-hour MTBF rating reinforce operational governance for long-lived storage fleets.

Key Applications:

• Enterprise RAID arrays
• JBOD enclosures
• Scale-out storage nodes
• Backup and archival repositories
• Object storage capacity tiers
