From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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:

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

There is no problem with having home on a different disk. But why do you want swap on the slower disk? These would benefit from being on the faster disks. Same with all the system binaries.

Personally I would put as much as possible on the faster disk and mount the slower somewhere that the speed matters less. Like for photos/videos in your home dir.

/boot can be anywhere though if you are getting a grub error that suggests the UEFI firmware is finding grubs first stage but grub is having issues after that. Personally I don't use grub anymore, systemd-boot is far simpler as it does not need to deal with legacy MBR booting.
