Product overview
WD40PURZ-85TTDY0 is a Western Digital purple 4TB 5400RPM SATA 64MB 3.5-Inch surveillance hard Drive. Rebuild time scales with capacity, so a large drive in a parity group is a longer window of exposure. This one spins at 5400RPM. Tell us the RAID level and group size and we will say plainly whether the geometry still makes sense.
The listed price is per unit and current; tell us the quantity and we will confirm what it holds at before you raise the order.

What you get ordering this from us
Ordered by part number
WD40PURZ-85TTDY0 is what is quoted and WD40PURZ-85TTDY0 is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
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.
Answered by a human
A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
Questions buyers ask about this part
Is WD40PURZ-85TTDY0 genuine and is the warranty intact?
Yes. Supplied new and unopened, so the manufacturer warranty and firmware update path stay supported. No grey-market stock and no refurbished units sold as new.
Will WD40PURZ-85TTDY0 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.
