Got the Framework 13 Ryzen 5 7640U when it was initially released (Batch 5 I think). Brought my own SSD (500gb I still had kicking around) and RAM (32GB). Only ever ran Linux (Arch) on it. Had a lot of issues at the beginning with suspend pulling lots of power and then (after some tweaking) suspend not being usable because at every wake the Filesystem was read-only. Also the boot option (efistub) would vanish if I hit Ctrl+Alt+Delete during boot (meaning I would have to boot from a live USB every time to fix it. After a while of this (and some troubleshooting) I switched the SSD (with another 1TB leftover from some other project but rather new) and the boot option issue stopped. After undoing my tweak for suspend, suspending now works and at least seems to be pulling less power. So had a bit of hassle at the beginning, now it’s just a great Linux laptop.
This. I have been running it the same way for some time now. Even if you change something on one machine and something else on another nextcloud will just happily inform you of the conflict and then you can open both databases and cherry pick. Never had corruption issues.
