My PC has M.2 Nvme SSD and HDD.
Tumbleweed is on HDD, and Windows 10 no SSD.
I am thinking about using only Tumbleweed and installing it on Nvme SSD.
Does Tumbleweed take care about everything regarding Nvme SSD or I have to manually do something, like special options in fstab or enable trimming?
I can’t get a clear picture reading online texts. Some mention separate tmp partition and noatime option.
Each of these partitions uses default options. Newbies may safely use defaults whenever applicable. You may consider switching the system partition from btrfs to ext4. If you stay with btrfs be prepared for doubled space requirements. My 60G are a very comfortable choice.
Furthermore, if you are into experimenting for performance benefits, this Wiki article about SSDs should have good information.
But as Karl Mistelberger wrote, the defaults are probably fine.
