TRIM
Usefull for SSD, thin-provisioned storage and virtual images.
Periodic TRIM
Preferred.
Ubuntu already has a service fstrim.timer setup. The timer runs weekly.
The timer relies on the timestamp of /var/lib/systemd/timers/stamp-fstrim.timer (which it will create upon first invocation) to know whether a week has elapsed since it last ran.
Continuous TRIM
Alternatively add a filesystem option discard in /etc/fstab.
