Product overview
ST18000NM003D is a Seagate 18TB 7200RPM SAS 12Gb/s 3.5-in HDD. Vendor-keyed firmware is the usual reason a mechanically identical drive is rejected by the controller, and a 18TB spare is not worth discovering that on. We check the firmware family against your controller before the drive ships.
Quotes are itemised down to the accessories, so nothing that is needed to make the part work is left off and discovered later.

What you get ordering this from us
Ordered by part number
ST18000NM003D is what is quoted and ST18000NM003D 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.
No substitutions without asking
If we cannot supply the exact code we tell you what we can supply and why, rather than shipping an equivalent and letting you find out.
Questions buyers ask about this part
Is ST18000NM003D 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 ST18000NM003D 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.
