Not just faster, 16GB difference since you don't actually get a full usable 240GB. I'd go for the MX100 as its newer.
I agree with you on size, but as far as value, its .33/gb, vs .44/gb, the problem im struggling with is, is the speed a big difference? If the mx100 is opening programs/games 1-5 sec faster, I would get the m500, but if its a 20sec difference, I'd get the mx100. So simply put, what type of speed difference is there?
