Is WUH721818ALE6L4 genuine and is the warranty intact?

Yes. Supplied new and unopened, so the manufacturer warranty and firmware update path stay supported. No grey-market stock and no refurbished units sold as new.

Will WUH721818ALE6L4 work in my server?

Send us the server model or service tag and we will confirm before you order. Part numbers alone do not always settle it — firmware revision and platform generation matter, and this is the check that prevents a return.

Do you accept purchase orders and quote at volume?

Yes. Purchase orders are accepted from qualified organisations, net terms are available on approval, and tiered pricing applies at quantity. Tell us how many you need.
