Totally agree with the enterprise level ssd's. But as far as the pro vs evo. In a mobile you should most definitely see the difference. Random access read/write on pro are almost double the evo. And the 3 bit's per cell cant really cant be compared longevity of the pro as the 3 bit technology is so new that any performance done cant be a real world. But, im not totally dissing the evo, I did just buy one. Sadly, for $100 less I did almost get the 500gb pro. Just firm believer of top performance at high quality, vs average performance at a budget quality.
I was just hoping that somehow the hours I spend daily on tech sites and forums, I had some how missed some talk about the 840 pro being released higher, or even the evo doubling storage. As for me, even though I just spent more on a ssd for my laptop than most average people spend on their entire laptop, if either the 840 pro came out with 1tb or evo with 2tb id be buying it to replace this new one as soon as they became available.
