Product overview
The Seagate Exos X20 20TB 7200RPM SAS 3.5-Inch HDD is supplied under part number ST20000NM004D. Carriers and caddies are chassis-specific and are almost never included with a bare drive; this is 3.5-Inch. Give us the server model and we will quote the carrier alongside it instead of letting it hold up the swap.
Priced per unit, with tiered pricing at quantity — send the number you need and we will come back with the banded price.

What you get ordering this from us
Ordered by part number
ST20000NM004D is what is quoted and ST20000NM004D 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 ST20000NM004D 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 ST20000NM004D 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. Purchase orders are accepted from qualified organisations, net terms are available on approval, and tiered pricing applies at quantity. Tell us how many you need.

Specifying a system, not just the part?
Bulk capacity usually sits behind the flash tier that feeds a training cluster rather than under it.
