Product overview
ST12000NM000J is a Seagate Exos X18 12TB 7200RPM SATA 3.5-Inch 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 7200RPM. 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 ST12000NM000J, not against a description of it, so there is no room for a substitution you did not agree to.
Volume pricing
The listed price is per unit; tiered pricing applies at quantity and purchase orders are accepted.
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 ST12000NM000J genuine and is the warranty intact?
Yes, new and sealed, with the Seagate warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
Will ST12000NM000J 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.
