Product overview
Part number WD4006FZBX identifies this Western Digital WD_BLACK 3.5-Inch gaming hard Drive 4TB 7200RPM SATA 256MB cache 3.5-Inch. Replacing a failed drive means matching interface, form factor and firmware to the backplane it is going into. This is a SATA unit. Send us the server model and we will confirm the fit rather than leave you to check it.
If you are buying a spare rather than a replacement, say so, and we will match the firmware family to what is already in the shelf.

What you get ordering this from us
Ordered by part number
WD4006FZBX is what is quoted and WD4006FZBX is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Volume pricing
The listed price is per unit; tiered pricing applies at quantity and purchase orders are accepted.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.
Questions buyers ask about this part
Is WD4006FZBX genuine and is the warranty intact?
Yes, new and sealed, with the Western Digital warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
Will WD4006FZBX 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.
