USB drives or memory are in the range of 10MB/s write and 15MB/s read. Since you need to both write & read to transfer a file, you are looking at about 7MB/s file transfer which is about 50Mb/s (wireless order of magnitude). Combined with the inconvenience, the benefits of this system are questionable.
