Just like any other storage device you could have fragmented files.
Flash memory is not "just like any other storage device". Most SD cards use wear leveling to remap sections of updated files to other locations without any visibility to the filesystem level. Defragmenting operations on such devices increases fragmentation. Flash memory does not have the seeking latency of rotating media, which is what defragmenting tries to address.
