A HD is generally for me first any HD no matter what the hardware setup is, since I don’t really talk about a hardware issue in general.
I have no “spinning” HD for MSFS.
The main data as well as my windows 10 system is based on an NVME.
The data we are talking about are on another NVME. Before, the data had been on an NVME and now they are again on an NVME (but (and this is the difference) the new NVME is even faster then the old one, that was the reasone why I repaced it.
