What drugs are you on man? SSDs are great for gaming especially with the arma engine as it has to read a large amount of files for the game. And no SSDs dont magically get full when you play a game...

I have the same problem exactly as you describe it. i also used to have this problem with the mod and specifically dayz commander. i solved the problem by lowering the max connections from daycommander, but i dont beleive its possible now from ingame. i strongly beleive thats the reason the router locks up for a few minutes.
