I just ordered my E-PM1. I now need to pick suitable storage for it. It claims to support UHS-I in the spec sheet, but would it make use of all this write speed? There's the SanDisk Extreme Pro 8GB UHS-I that I'm considering, but I'm wondering if that would be a waste of money. Should I stick with class 6 or 10 from a reputable manufacturer like SanDisk, instead? I'm a total newb when it comes to photography. This will be my first (semi-)serious camera, so any advice would be much appreciated. Thanks!
