While using TRIM can make a difference.  IF your hard-disk is full
enough, TRIM won't help.  IOW the SSD has to have enough extra space of
its own in order to provide good performance when it's "full".

For this reason, I stopped worrying about TRIM (actually I stopped
worrying about it right around the time it started to be somewhat
usable without jumping through too many hoops).

IOW, I now use my SSDs without any special configuration and I haven't
noticed any performance issue (and I think we should *expect* the
performance to be good in such a situation).


PS: My SSDs include an old 120GB Samsung, a Samsung 840 of some sort,
and a 240GB Mushkin.
