What MicroSDHC do you recommend I use? I got a 8GB Sandisk MicroSDHC Class 6 card originally but I just found out that the write speed doesn't matter and the read speed does. Apparently something is up because I was getting random lockups and now I think that is what is causing it. I would like it to be 8GB or larger if possible. Oh and what is the best way to find out the read/write/random speeds for my MicroSDHC?
