Okay, that lead me to consider TRIM for my SSD... everything I need is covered just fine, but the following blog post might be useful to some: http://blog.neutrino.es/2013/howto-properly-activate-trim-for-your-ssd-on-linux-fstrim-lvm-and-dmcrypt/ On my Linux Mint 18.3 laptop, I already had discard in /etc/crypttab (I never put it there). It was also already enabled in my /etc/lvm/lvm.conf file as well, (again I didn't put it there). And a very simple weekly job (compliments of Mint team I guess) also takes care of fstrim for all file-systems that support it as follows: # cat /etc/cron.weekly/fstrim #!/bin/sh # trim all mounted file systems which support it /sbin/fstrim --all || true Cheers AndrewM
