Product overview
WD40PURZ is a Western Digital purple 4TB surveillance 5400RPM class SATA 6Gb/s 64MB cache 3.5-inch hard Drive. Carriers and caddies are chassis-specific and are almost never included with a bare drive; this is 3.5-inch. Give us the server model and we will quote the carrier alongside it instead of letting it hold up the swap.
Priced per unit, with tiered pricing at quantity. Send the number you need and we will come back with the banded price.

Questions buyers ask about this part
Is WD40PURZ 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 WD40PURZ 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.
