I ordered a new A2Ki to replace my R4 (oops!) and it should be arriving within the new few days. So I'm buying a new micro SDHC to prepare. I noticed I could get a 8GB for 11 bucks on Amazon and that would be a sweet deal. But I noticed its only a class 2 which is 2mb/s transfer rate, and class 4 and 6 are respectively 4mb/s and 6/mbs. The 6/mbs 8GB SDHC is 20 which is still not bad but less than 11. I'm currently using the past recommended fast Kingston SD-C02G 2GB that everyone said to get back then so Castelvania wouldn't lag and games as such. Does anyone know what class that card is? I tried finding it online and I can find it but no info on the class for that serial. Basically am I going to see any lag in games if I go with a class 2 besides castlevania? I don't mind if it takes an extra few seconds to boot the game, just that if the game actually lags in game. Are class 2's okay? Should I splurge on the class 6? Does it matter? Thanks for any help.
