SD card replacement

I’ve seen a few posts related to using up to a 32 GB SD card, but I haven’t noticed any posts relating to the type of card used. Has anyone used the ultra SD class 10 cards? Should I stick to the class 4?

There are some posts in here about comparing the class 4 to 10 cards speeds. The class 10 cards seem to have a very slight speed edge. Either class will work and unless the ever-so-slightest speed bump matters that much, you’re probably just as well off with the class 4 cards. If you’re worried about the number of songs that will fit on a 4Gb card, I don’t think you have much to worry about. I have several hundred songs on my 4Gb SD card along with a dozen kits (with bass) and I’m just now approaching the capacity of the card. 16G is probably more than you’ll ever be able to fill. The key is backing up your project.

Thank you!
