Multiple moOdes, one hard drive - what's the best option?

[wadada]

I was also not sure and tried it out over some months (SMB/NFS to NAS) Both ran quite smooth. From time to time small issues. But this could be the router, NAS, etc... In general I could not tell which protocol is more stable/unstable. In the end I decided for NFS. Reason is that I do only have Android/Linux devices in the household that do connect to the NAS. And the connection from my main desktop to the NAS is definetly more stable via NFS.
