For any SSD compatible partition created by the Ubuntu installer or gparted or the Disk Manager then the appropriate TRIM option should be set.

It is relatively easy to test if a drive is a SSD (sda in this example):

cat /sys/block/sda/queue/rotational

0 (zero) means non-rotational (SSD), 1 means a "normal" rotational drive.

Any non-TRIM filesystem installed on a SSD should also be flagged with a big warning message that doing rewrites on this non-TRIM partition may eventually use up all the empty blocks and cripple SSD performance on ALL partitions.
