No, the "ssd" mount parameter has nothing to do with TRIM.
The "ssd" mount parameter adjusts a couple of tuning parameters where
the default setting is designed to improve performance on spinning HDD,
and instead tunes for the random-access ability of an SSD.
The ssd option is automatically enabled if the kernel detects that your
drive is an SSD (you can check with 'cat /proc/mounts').
The discard option is not currently automatically enabled; I think there
may have been some performance issues in certain cases with drives that
have slow trim implementations. But feel free to give it a try.
