hi
want to enable ssd trim function?
we need to find out that your ssd supports this function:
hdparm -I /dev/sda | grep -i trim * Data Set Management TRIM supported * Deterministic read data after TRIM
just edit your fstab or remount your filesystem with the option discard
here ist my fstab
UUID=a3804d35-2e8f-4acf-8d9d-f33940a61f5d / ext4 noatime,barrier=0,discard,errors=remount-ro 0 1
here some nice reference (german):

have fun!
