I'm in the market for a micro sd card for my G2x and I was wondering what everyone is using or would recommend. And as far as class classification, I've seen class 4 and class 10, which one would work best on G2x? Thanks.
The higher the class the faster the speed. I would go with at least a class 4 if you're transferring files around a lot. If you're not doing that then class 2 would be fine.
I would find the best price/performance ratio that you can afford. Once you get into higher capacities and faster classes the $$$$ goes up quick.
Please be careful purchasing a card. There are many fakes out there. Make sure you test it for capacity as soon as you receive it. I have purchased 3 fakes in a row. Luckily, I was able to get a prompt refund in each case.
