WUH721816ALE6L4 – 16TB 7200 RPM SATA 6Gb/s 3.5-Inch Ultrastar He16 Enterprise Hard Drive

The WUH721816ALE6L4 is a 16TB enterprise-class hard drive from Western Digital’s Ultrastar He16 line, offered through our wholesale channel for resellers, system integrators, and IT procurement teams building capacity-tier storage, bulk archival pools, or scale-out NAS backends. Helium-sealed construction delivers high per-drive density with stable thermal behavior, making it a strong repeat-purchase SKU for rack-scale deployments.

Units are sourced in consistent factory batches, and we maintain stock in standard pack quantities with regular replenishment cycles. For volume orders, we can align firmware versions and manufacturing dates within a single shipment so that integrators deploying multi-drive RAID groups avoid revision mixing across their pools. Buyers running IOPS-sensitive workloads should note the 7200 RPM spindle class and plan SSD tiering accordingly.

Good to know for resellers and integrators

• High-capacity 3.5-inch SATA drives are broadly supported, but confirm backplane, HBA, and firmware support for 16TB capacities on older platforms before placing bulk orders.
• The He16 targets dense enterprise capacity tiers with a 550 TB/year workload rating — a duty cycle above NAS-oriented lines such as IronWolf or surveillance lines such as SkyHawk, which matters when advising downstream customers.
• All shipments carry CE, FCC, and RoHS compliance documentation to support export and customs clearance in major destination markets.
• Warranty and RMA handling is centralized through our channel desk; failed units are processed against the original invoice number, so resellers can pass through claims without contacting the manufacturer directly.
