Not my experience. It may be true for some really cheap devices, but normal USB keys seem to just get really slow, probably due to having had their flash rewrite algorithm tuned for FAT accesses.
I *do* suspect that to see the really bad behavior, you don't write just one large file to it, but many smaller ones. "git clone" will check out all the kernel tree files, obviously.
