Product overview
Western Digital lists WD43PURZ as a purple surveillance hard Drive 4TB SATA 256MB cache 3.5-Inch. Rebuild time scales with capacity, so a large drive in a parity group is a longer window of exposure. Tell us the RAID level and group size and we will say plainly whether the geometry still makes sense.
Send the quantity you need and we will come back within 48 business hours with availability confirmed, not estimated.

What you get ordering this from us
Ordered by part number
The order is placed against WD43PURZ, not against a description of it, so there is no room for a substitution you did not agree to.
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.
Firmware family matched
A mechanically identical drive with the wrong firmware is rejected by the controller; we check the family, not just the capacity.
Questions buyers ask about this part
Is WD43PURZ 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 WD43PURZ 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.
