As far as documents go, they clearly state the 20mb/s A21 model is class 6

but I cannot see anywhere where they mention the 30mb/s A31 model, so my question is, it is class 6?

the difference in price is unsubstantial to me, around $4?

so the bottom line, which one would you recommend to me?

ty

buy faster if you need fast card or if you dont care much about $4

I would mainly I'm just curious to know/find out if both cards are indeed Class 6

in that case I would get 30mb/s for $4 more, yes

do they say theyr class 6? enyway what does it matter what class are they? it doesent effect actual writing speed. mb/sec and memory size is what matters

Well thanks for the info
