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.
