Product overview
This is the Seagate 20TB 7200RPM SAS 12Gb/s 3.5-in HDD, order code ST20000NM002D. Carriers and caddies are chassis-specific and are almost never included with a bare drive. Give us the server model and we will quote the carrier alongside it instead of letting it hold up the swap.
Quote requests are answered within 48 business hours, with availability confirmed before you raise a purchase order rather than after.

What you get ordering this from us
Ordered by part number
ST20000NM002D is what is quoted and ST20000NM002D is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Firmware family matched
A mechanically identical drive with the wrong firmware is rejected by the controller; we check the family, not just the capacity.
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.
Questions buyers ask about this part
- Is ST20000NM002D 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 ST20000NM002D 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.
