MY first card died. It was an 8GB class4 microsdhc card from Silicon Power. I had video slowdown in some games' videos, so I'm glad it died because I could return it and get the money back which I plan to spend on a faster card if that's what caused the problems I experienced. I found a Kingston 8GB class6 for roughly the same price I paid for the other one. What do you think, Is that a good option for the ak 2.1? If not, what should I look for?
