Might be late to the party, but I just discovered you can do this. Super simple and easy to do.
After having a read of the linked page, I backed up and just used this option:
https://wiki.archlinux.org/title/Profile-sync-daemon
Installed, created config, and enabled service:
systemctl --user enable psd.service systemctl --user enable psd-resync.service
I definitely notice an increase in speed and less SSD usage should hopefully increase lifespan.
I’m sure there would be options for alternative distros, anything using Systemd should be able to use the daemon.
Nah i think the right way to do it is go to some site (you can Google some) and download some RAM. They even make the link flash so its easy to find. If you need more RAM just download some more
