WUH722020BLE6L4 WD Ultrastar DC HC560 20TB SATA 512 MB 3.5" Server HDD

High-Density 3.5in Enterprise SATA HDD for scale-out storage nodes with the WUH722020BLE6L4

The WUH722020BLE6L4 is a 20TB datacenter-class 3.5in internal HDD designed for capacity-first rack servers and storage nodes where predictable throughput and sustained duty cycles are mandatory. As a CMR drive in the WD Ultrastar DC HC560 family, it supports consistent write behavior under mixed workloads and rebuild operations, aligning well with modern storage stacks that depend on stable latency characteristics.

With a SATA 6Gb/s interface, the WUH722020BLE6L4 integrates cleanly into widely deployed server backplanes and JBOD enclosures, enabling cost-efficient expansion without changing the host PCIe topology. The 512e sector format supports broad OS and controller compatibility while maintaining 4K-aligned efficiency, and the 7200 RPM profile with 512MB cache is tuned for sustained sequential performance in bulk tiers. In scale-out architectures, the WUH722020BLE6L4 is typically paired with CPU-dense storage nodes and high-memory configurations to accelerate metadata, caching, and erasure coding while keeping capacity on reliable spinning media.

Why Choose the WUH722020BLE6L4?

The WUH722020BLE6L4 delivers an enterprise-appropriate density-to-bay ratio for backup, archive, and object storage, reducing rack footprint and power per TB at the node level. Its datacenter reliability design and high MTBF target help standardize fleet operations, while SATA connectivity keeps replacement logistics and interoperability straightforward across heterogeneous server generations.

WD’s Ultrastar engineering emphasizes controlled vibration behavior, thermal stability, and qualification for continuous operation, supporting consistent performance in multi-drive enclosures and aligning with modern datacentre serviceability expectations. For capacity tiers where deterministic behavior matters more than peak IOPS, the WUH722020BLE6L4 provides a balanced, operationally efficient profile.

Key Applications:

• Backup repositories
• Archive and compliance storage
• Object storage clusters
• Scale-out NAS capacity tiers
• General-purpose enterprise bulk storage
