Your two slowdowns from what you have listed are "USB hub" and FAT32. Fat32 does not store the file records that rsync uses on Unix filesystems to know that a file has changed or not... so you are doing pretty much tar cf - ./* | (cd /mnt/fat32disk; tar xf -). The hub adds insult to injury in that you have two polling layers going on but I expect it might only add 20 minutes to the write.
Make the USB key ext4 without a journal and you should see a large improvement. -- Stephen J Smoogen.
