Product overview
The HPE 12TB 7200RPM SAS 3.5-Inch hard Drive is supplied under part number 881781-B21. Rebuild time scales with capacity, so a large drive in a parity group is a longer window of exposure — this one spins at 7200RPM. Tell us the RAID level and group size and we will say plainly whether the geometry still makes sense.
If you are buying a spare rather than a replacement, say so — we will match the firmware family to what is already in the shelf.

What you get ordering this from us
Ordered by part number
881781-B21 is what is quoted and 881781-B21 is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.

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 881781-B21 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 881781-B21 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. We quote against a purchase order and hold the price for the quote period, with tiered rates at quantity. Net terms are available once the account is approved.

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