Using GUI still ads the mount point and chosen rules to fstab so it doesn’t matter how it got there, if it is in the fstab it will persist.

Still, the location. Everywhere I’ve checked, it just stated to go for /mnt/ and voilà. I guess the main thing is understanding what mounting is, as Windows just shows you a partition and treats it as its own tree, UNIX system treats everything as one giant tree, growing from / “root” directory. Technically, probably, you can mount it almost wherever you want to, but /mnt/ is just the “good / common practice”.

Both of my SSDs are mounted via fstab in /mnt/ with x-gvfs-name so it looks a bit tidier.

But if this is not the way, I need some more education.

You are now a Certified Rejector. Stay sharp, keep the wheel rolling.

My preference is „bare metal” approach, then I really know if everything is working as it should, so I had a separate drive for Linux installation at the beginning and got to my other drives by just mounting them as NTFS.

But, finally I am at the point of no return for some time now, the old Windows drive is not even inside of my PC and the other drives are ext4 already.

For a quick check Live CDs/USBs are totally fine but not fully representative.
