I have a laptop and the manufacturer gave me this information on request: (see picture)
Does this https://www.amazon.de/...0784SY515/ fit or do you have a better one?
Nope, wouldn't go. You need M.2 PCIe, not M.2 SATA
Reach for the Kingston A2000
Don't I need the 2230 or 2280 somehow?
2230 or 2280 only describes the dimensions. The A2000 is ne 2280
