your not paying so much for the space as you are the speed.
the speed they run at makes you wish all your drives we're that fast. you would need to test one out first to really understand....but now the prices are jumping up. my vertex cost me 324 bucks last year...they now cost 550 bucks. and they are better than most of the intel drives do to writing speeds. intels read hella fast, but we're writing far slower. (speculation now, they may have caught up and i haven't check lately)
and you would just use it as your os drive and use your 1 tb drive as your storage...(suggestions only)
