This may have been answered in other forums. But as well all know the Archos 70 and 101 can take microSDHC cards. Does the class rating for these cards really matter? I mainly used class 4 for my Creative Zen and they worked just fine. The class 4 microSDHC cards I got for my Archos 70 work fine too. I was wondering if the higher classes would show any improvement in video playing\music playing.
