Well the thing is that i see a lot of tests on the web and while the intel isn't the fastest , in real use it shine somtime better
The good thing about samsung also is the fact that they developped they're own controller witch gives them a full control and support with a better indepandance and so quiker reactivity
By the way may i ask you witch one you would take between a crucial and a smasung 512 GB both ?
Also have you already use only one ssd (or 2 in raid) and use it exclusively for all (data and software) ? if yes how does it performed versus 2 dedicated (ssd or ssd +regular)
Because seeing how great they are , i wonder if in some near futur , we will still have to use multiple drives (supposing that the price/gb drop more
