Product overview
The Western Digital elements portable 4TB external hard Drive USB 3.2 gen 1 / USB 3.0 is supplied under part number WDBU6Y0040BBK-WESN. Vendor-keyed firmware is the usual reason a mechanically identical drive is rejected by the controller, and a 4TB spare is not worth discovering that on. We check the firmware family against your controller before the drive ships.
Quote requests are answered within 48 business hours, with availability confirmed before you raise a purchase order rather than after.

Questions buyers ask about this part
Is WDBU6Y0040BBK-WESN 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 WDBU6Y0040BBK-WESN 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, POs from qualified organisations, net terms on approval, and banded pricing once the quantity is worth banding. Send the number and we will price it properly.

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