###A few key tips

For example, if you are using 8gb cards that are all exactly the same make and model, it shouldn't be much of a problem. The issue is different manufacturers when they create an 8gb sd card, it may be a few kilobytes bigger than that other brands 8gb SD card. So if you use the bigger one to cr
