What you get ordering this from us
Ordered by part number
Quoted and supplied against WUH721818AL5205 specifically, so what arrives is what your build sheet asks for.
Firmware family matched
A mechanically identical drive with the wrong firmware is rejected by the controller; we check the family, not just the capacity.
Spares held to a fleet standard
Tell us the chassis you run and we will keep the spare consistent with what is already in the shelf.
Questions buyers ask about this part
- Is WUH721818AL5205 genuine and is the warranty intact?
- Yes. It ships new in Western Digital packaging, which is what keeps the warranty and the firmware entitlement valid. Anything we cannot supply that way we tell you about before you order.
- Will WUH721818AL5205 work in my server?
- Send the server model or the shelf it is going into. Vendor-keyed firmware is the usual reason an identical-looking drive is rejected, so we check that alongside interface and form factor.
- 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.

Specifying a system, not just the part?
Bulk capacity usually sits behind the flash tier that feeds a training cluster rather than under it.
