TRIM does not even matter all that much.

Its really not that difficult to expolain why defrags kill SSD.

SSD use chips, these chips have a sertain limit of usage cycles.
Every time you delete something, one cycle of that particular chip the file is stored on decreases by one.
Everytime something new is written to them, the same thing happens, uses one cycle.

Now defragging, is nothing more but moving files around for them to be closer together so they can load things faster, for an regular HDD this si great as the harddrives laser doesnt have to much as much as otherwise, greatly reducing searcxh times for files.

With SSD however, all is electronical, there is no search time to begin with, hence defragging is nothing more but killing your cycles and reducing the lifespan of the SSD.

Now when a chip reaches its limit, the files on it are still available to be read.
You simply can not write new stuff to that particular chip anymore nor delete them files on that chip anymore.

Now there are several types of chips, one lasting far longer then the other but also comes at a greater price.

Take a god look here to find out more about such.

Now knowing all of that, and if you use your brain properly, you can EASILY get more then 7 years out of your SSD if you manage it correctly.

And defragging them, gains you absolutly nothing but a decreased number of cycles.
