Some USB 3 sticks are very slow on random writes - even very 'fast' ones.
Can you run a benchmark on your usb stick (e.g. Crystal DiskMark) - what are random 4k rd/wr times?
e.g. Lexar Jumpdrive LJDP20-128Gb is a very fast USB 3 drive for synchronous transfers (400MB/s), but the 4k random rd/wr times are terrible and it is very slow when used as wintogo or full OS or persistence!
