Re: How big is your MicroSDHC card and speed?
The class is the MB/s of transfer speed. Class 2 is 2MB/s, 4 is 4MB/s, etc.
I haven't seen anything over 4MB/s for micro SD cards (at least not for 8GB and up), but yes, it does make a difference. It's not a noticeable 100% increase in speed, but it is noticeable.
I'm currently just running my 4GB class 2.
Class 4's are generally quite a bit more expensive than the class 2's.
