I've read the other answers you got in this thread. I've been using SSD drives nearly two years, all of its partitions are mounted with discard enabled, and didn't encounter any sideeffects. So despite some folks are advising against using the discard mount option, it depends on what's important for you and how your system behaves. In short: you have to try for yourself what fits your needs. Btw: great that there's proof for at the discard mount option can result in lower performance. But, as always, this doesn't take into account if and to what degree this affects real life behaviour, which also varies between the respective real life situations...
If you can afford to leave enough free un-partitioned space on the SSD, then you don't need discard or fstrim as the un-partitioned space acts as extra over-provisioning. Have a look at this blog post[1] by Kent Smith from LSI (they make the SandForce flash controller on Intel SSD's) and the comments on it, it was very informative (for me at least).
