You surely don't need to avoid fragmentation on a random-access device. What does it matter where the next block is located on the media when the access time to the next block is the same no matter where the current block is located?


Not all flash is truly random access. NAND flash, in particular, has peculiar rules about rewriting data blocks once they've been written that makes approaches that minimize metadata writing and fragmentation very important for performance and efficiency.
