Product overview
Western Digital lists HUH721212AL4200 as an Ultrastar DC HC520 12TB 7200RPM SAS 3.5" HDD. 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.
Ask for the datasheet and firmware notes with the quote; we would rather you check our claim than take it.

What you get ordering this from us
Ordered by part number
HUH721212AL4200 is what is quoted and HUH721212AL4200 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.
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 HUH721212AL4200 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 HUH721212AL4200 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.
