I haven't. and I'm only getting 1 SSD.
i dont even know what trim is, I haven't read up on it yet.
short version, what is it? and is it worth using?
From what I know, TRIM is just a command that permanently wipes the data off the SSD when its deleted after a period of time, so when new data is written in its a quick write, not a slower re-writing over existing data.
without TRIM, you'll have to wipe the SSD every couple of months manually or the performance will start deteriorating.
