Is WUH721818AL5205 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 WUH721818AL5205 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.

Product overview

WUH721818AL5205 is a Western Digital Ultrastar 18TB 7.2K SAS 3.5-In HDD. Replacing a failed drive means matching interface, form factor and firmware to the backplane it is going into; this is a SAS unit. Send us the server model and we will confirm the fit rather than leave you to check it.

We return an itemised quote within 48 business hours, and we say plainly when a part is constrained rather than quoting a date we cannot hold.
