Western Digital Ultrastar WUH722018CLE604 – 18TB 7200 RPM SATA 6Gb/s 3.5-Inch Enterprise Hard Drive

The Western Digital Ultrastar WUH722018CLE604 is an 18TB enterprise-class 3.5-inch hard drive that we supply to resellers, system integrators, and IT procurement teams building data center, hyperscale, and high-density storage solutions. Positioned above WD’s NAS (IronWolf/Red) and surveillance (SkyHawk) families, this SKU is intended for continuous, heavy-duty deployments such as object storage, cloud tiers, and large-scale RAID arrays. Buyers should note that as a mechanical CMR drive it serves capacity-optimized roles rather than latency-sensitive workloads, where SSDs remain the better fit.

Sourcing & Supply Overview

We stock the WUH722018CLE604 in wholesale quantities with batch-consistent inventory — units within a single order are drawn from the same manufacturing lot and firmware revision wherever possible, which simplifies qualification and RAID deployment for integrators. Current stock levels and incoming shipment schedules can be confirmed with our sales desk before you commit to project timelines.

All units ship with manufacturer warranty coverage, and our RMA process is handled directly through our warehouse to minimize downtime for resellers: defective drives are validated, cross-shipped or credited per agreed terms, and tracked batch-by-batch. Typical order-to-ship lead time for in-stock volume is short; for large or recurring orders we can reserve allocation on scheduled production releases.

Shipments are export-compliant, with CE, FCC, and RoHS documentation available on request for customs and tender submissions. Whether you are a regional distributor filling reseller stock, a system integrator building rack-scale storage nodes, or a corporate IT buyer standardizing on a single enterprise HDD SKU, this drive supports high-density enclosures where the 550 TB/year workload rating and 2.5 million hour MTBF matter. Confirm the exact model number (WUH722018CLE604), sector format, and firmware when ordering, as enterprise drives ship in multiple interface variants. For volume pricing and allocation, request a wholesale quote.

Good to know

• The SATA 6Gb/s interface integrates easily into most servers and JBOD enclosures; integrators should verify backplane support for helium-sealed high-capacity drives and confirm RAID controller tolerance for 18TB sector layouts before deployment.
• Within Western Digital’s portfolio, the Ultrastar line targets enterprise and hyperscale duty cycles — heavier rated workloads than desktop or NAS-consumer drives — making it a dependable standardized SKU for rack-scale rollouts.
• Bulk-pack and retail-boxed units may both be available depending on batch; confirm packaging format, batch consistency requirements, and stock availability with our team before committing to large quantities.

Wholesale & Procurement Notes

• MOQ negotiable depending on SKU availability and destination market.
• Tiered volume pricing available — request a quote for project or recurring-order rates.
• Typical lead time: 1–3 business days for in-stock volume; 2–4 weeks for allocation on scheduled releases.
