See http://danweinreb.org/blog/using-solid-state-disks-on-linux and other blogs/articles.
Ted T'so wrote an excellent item on it, unfortunately it appears rather difficult to find now.

Anyway the short version is there are things to consider when partitioning the SSD and when initialising a filesystem on it - those things can't be tweaked later. That's mostly for speed.

And then you have mount options like noatime and a few other tricks that reduce unnecessary writes.
