Wierd question, but what is the diffrence between fat16 and fat32?
Is one better than the other? I formated my sd card for fat32 but the info on my super everdrive says fat16/fat32 dose that mean both are there?
Just trying to get the best out of my card.

fat16/fat32 meant that cat supports both. cards bigger than 2gb req fat32, for small cards can be used 16 or 32, does not matter

There is also cluster size differences. FAT32 is more efficient IIRC.

Smaller clusters are more efficient in terms of disk space utilization. Larger clusters are more efficient when it comes to read performance. With large clusters you can read more data per READ_MULTIPLE_BLOCK command, i.e. there's less overhead when reading (though for completely non-fragmented files it's possible to get the same level of performance regardless of the cluster size).
