ST12000VN0008 is Seagate IronWolf 12TB SATA-6G. 3 of its 5 segments are defined in Seagate's published documentation and decoded below; for the rest we have not found a defining document, and they are marked as such. No live listings right now - the reference material below still applies.
| Segment | What it means | Source |
|---|---|---|
| ST | Seagate product prefix. | Seagate |
| 12000 | Capacity field. 12000 denotes 12TB of formatted capacity. | Seagate |
| VN | IronWolf NAS family. | Seagate |
| 000 | Not sourced - we have not found a Seagate document defining this segment. | Not sourced |
| 8 | Not sourced - we have not found a Seagate document defining this segment. | Not sourced |
We decode only what the manufacturer documents. There is a large body of community knowledge about the undocumented segments above, much of it probably right, and none of it published by Seagate - so it does not appear in this table. A reading nobody can check does not belong in a column headed “what it means”. Grammar reference: Seagate - product part-number and model-number decoding.

No seller we track has ST12000VN0008 in stock right now. That describes today's listings only - it says nothing about whether the model is discontinued. We are not going to fill this space with something else and call it a match. The decode, specifications and sibling table above are the reference answer for this part number and remain accurate whether or not anyone is selling one today. If you need the capacity rather than this specific part, the alternatives below are what is actually buyable.
A manufacturer part number does not imply a manufacturer warranty, and this is where part-number buyers lose the most money. OEM stock, integrator pulls and gray-market units all reach the market under the maker's own numbering. Retailers selling them sometimes state plainly that the manufacturer warranty is none; others simply do not mention it, which is not the same as it being covered.
Coverage attaches to the individual unit and its serial number, not to the part number. That means the only reliable answer comes from the manufacturer, about the specific drive you are being sold.
Ask the seller for the serial number before purchase, then enter it in Seagate warranty checker. We link the tool rather than showing a result here, because the answer depends on the individual drive and only Seagate can give it.
A seller warranty is a different promise from a different company. What each warranty tier actually covers · Verify on arrival

The part number cannot tell you - coverage follows how the unit entered the market, not its designation. We track no live listing for ST12000VN0008 right now, so there is no condition evidence to report either way. Check the specific serial with Seagate's own tool, linked in the warranty section on this page.
