Are you sure of this? I remember from a few years back for a project at work 
it was understood that compact flash was the only card that did wear levelling 
internally and that is why it also was so much more expensive. I know most of 
USB memory sticks do it these days so it cant be that expensive any more. If 
true then this is really good news. One will not need to bother too much with 
having to use a file system which does wear levelling for any project that uses 
a SD card.
