I’m experimenting with f2fs (the flash-friendly file system), but recently ran into a road block with it: it does not support shrinking. Ooops, so now I can’t enlarge / on my mini PC, because /home is f2fs. > NOTE: With LUKS encrypted partitions you have to pay particular care - TRIM > can compromise the security of your data and LUKS devs warn about it. This is for people who not only don’t want to have their data leaked, but also the information how much data is on their drive. As a private person that does not do any really dangerous business like politics, leaks and so on, this is an irrelevant attack vector for me. > However, on a drive with a lot of re-write ops you will at some point need/ > want to run fstrim. In this case you'll have to run cryptsetup with '--allow- > discards', before you run fstrim. You can make --allow-discards a permanent option, if you combine it with --persistent.

Steve Gibson, the author of SpinRite, had testimonials in his Security Now podcast of people using his tool on old SSDs that became very slow. Afterwards, the SSDs were back to their former glory. I guess because the tool read it from start to finish so the controller was forced to check every cell (that was in use). > You probably want to alter the cache path for your browser from the SSD drive > to your RAM (tmpfs), especially if you have a lot of RAM. Ouh yeah, firefox writes a backup of its internal state every 15 s or so. If you leave many tabs open, this amounts to many 100 kB minute.
