Product overview
ST18000NM000D is a Seagate Exos x20 18TB 7200RPM SAS 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.
Tell us the deadline you are working to and we will say whether it is achievable before you commit to it internally.

Questions buyers ask about this part
- Is ST18000NM000D genuine and is the warranty intact?
- Yes. It ships new in Seagate packaging, which is what keeps the warranty and the firmware entitlement valid. Anything we cannot supply that way we tell you about before you order.
- Will ST18000NM000D 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.
