WUH722020ALE6L4 WD Ultrastar DC HC560 20TB SATA 512 MB 3.5" Server HDD

High-Density 3.5in Datacenter SATA HDD for 24x7 Bulk Storage with the WUH722020ALE6L4

The WUH722020ALE6L4 is a 20TB WD Ultrastar DC HC560 enterprise HDD engineered for capacity-first storage tiers in modern server and JBOD architectures. Designed to sit behind x86 CPU platforms via standard SATA backplanes and HBAs, the WUH722020ALE6L4 enables predictable performance for sequential and mixed queue-depth workloads while keeping drive-count and rack footprint under control.

For storage controllers and expanders, the WUH722020ALE6L4 aligns with common PCIe-based HBA topologies by providing a stable SATA target for high-port-density enclosures and scale-out object repositories. CMR recording with EAMR and a 512 MB cache supports consistent write behavior in RAID/ZFS/erasure-coded layouts, while 4Kn formatting with 512e emulation simplifies integration across operating systems and storage stacks. A helium-filled 7200 RPM design optimizes power efficiency and thermals, supporting sustained duty cycles in dense chassis and cold-aisle datacenter environments.

Why Choose the WUH722020ALE6L4?

The WUH722020ALE6L4 delivers a strong density-to-serviceability profile for nearline tiers where capacity scaling, operational stability, and predictable rebuild characteristics matter. It is well suited for standardized fleet deployments, supporting controlled growth in multi-shelf JBOD and software-defined storage nodes with enterprise reliability expectations.

WD Ultrastar engineering prioritizes long-life mechanics, tight manufacturing tolerances, and datacenter-aligned validation for continuous operation. The platform’s reliability targets, secure erase capability, and integration-friendly sector options support governance and lifecycle processes in enterprise storage environments.

Key Applications:

• JBOD expansion shelves
• Object and nearline storage
• Backup and recovery repositories
• Content archives and data lakes
• Scale-out software-defined storage
