Hey folks. I recently got an old X220 with an mSATA SSD. I plan to to install Linux on there. It doesnt matter which OS: Debian, Ubuntu or Arch. The machine is so old that all distros play nice with it.

Anyway, the speed on the mSATA is slower than the 2.5 SSD. So I want to know if is it possible to have your /boot, /efi, swap on the mSATA. Then, the /home on the 2.5 SSD? Any problems with this setup and if anyone tried it before?

Now, for the reasons why I use mSATA instead of just putting Linux on 2.5 SSD:

  1. the mSATA is Samsung, pretty rare nowadays. The health is still very excellent. I checked with CrystalDiskInfo. So might as well use it.

  2. My X220 has a problem finding out grub if installed on the 2.5 SSD. It’s literally a 50/50 chance it can find grub properly. So:

a) you installed Linux on 2.5 SSD, reboot.

b) grub error screen

c) restart

d) boot into Linux well

Note at d) if I do anything to restart/shutdown the computer, you are back at step b) and require another reboot to reach Linux.

Any advice is welcome.

    I believe that the only FS that absolutely need to be on the root partition are /etc and /var. The rest can be anywhere else with various degrees of tinkering. For /home to be moved, you should just need to edit your fstab (or your systemd mounts, depending on your distro).
