Micro sd card help

how do i tell what class rating my card is and what range of ratings is good?edit nvm lol i found itbut one more thing mine is a class 4 8gig is that good enough for pokemon black 2 on acekard2i?

it should be, im running it with little to no problems now

I have used samsung 16gb class 4 with no problems so 8gb class 4 should be even better.I do however use class 10 16gb now and just ordered two 32gb class 10, I don't notice any difference between class 4 or 10 in the 16gb cards playing roms, but do notice a little faster rom transfer from pc to TF.
