I have a corsair force gt (the red one) its 60gb and after my os install i have roughly 4-2gbs left and i wanna buy a new ssd to and raid it to my existing one so i have more space. So do i need to buy the exact same one? do the speeds need to be the same? Do they both have to use the same interface (sata III)? PLease let me know also im new to raiding so any tips on raiding ssd's or guides would also be greatly appreciated.
