WUH722020BLE604 – 20TB 7200 RPM SATA 6Gb/s 3.5-Inch Ultrastar He20 Enterprise Hard Drive
SKU: 3634
The WUH722020BLE604 from Western Digital’s Ultrastar He20 line is a 20TB helium-sealed, 7200 RPM SATA 6 Gb/s enterprise drive that we supply in volume to resellers, system integrators, and data-center procurement teams. With a 550 TB/year workload rating and 2.5 million-hour MTBF, it is a proven SKU for capacity-tier object storage, backup targets, and large-scale NAS/enterprise arrays. Buyers whose deployments require throughput beyond the SATA 6 Gb/s ceiling can be quoted SAS variants from the same family on request.
Stock is held in bulk and released in consistent single-batch allocations, so integrators deploying mixed racks receive uniform firmware and date codes within an order. Each unit ships in original factory packaging with full manufacturer warranty coverage; our RMA desk handles defect claims directly with the distributor, minimizing turnaround for channel partners. Standard export documentation (CE, FCC, RoHS compliance declarations) accompanies every shipment to support customs clearance in major destination markets.

Deployment & Channel Guidance
- Compatibility: fits standard 3.5-inch SATA 6 Gb/s bays; advise end customers to verify backplane and HBA support for >16TB-class drives before large rollouts.
- Positioning: enterprise-capacity tier, above NAS-oriented IronWolf-class products; pairs with SAS-interface Ultrastar variants for bandwidth-sensitive projects.
- Order accuracy: confirm the exact model string (WUH722020BLE604) on all quotations — Ultrastar drives ship in multiple interface/firmware configurations that cannot be mixed interchangeably in fleets.
