Shouldn't "discard" be set to make TRIM work anyway, even with fstrim? man mount says for "discard": "Controls whether ext4 should issue discard/TRIM commands to the underlying block device when blocks are freed." Sounds like TRIM-commands wouldn't get through to the SSD when "discard" is not set. Still wondering. Stefan
