I have defragged flash drives before but it's pointless, seeing as it's not a mechanical hard drive that has any access latency - as I understand, flash can access data at the same rate anywhere in memory since electrical impulses are instant. Hard drives of course have to go distances to grab data, hence the need to defrag them. This also needlessly eats up your limited number of read/write cycles of the flash memory.
