I've been reading guides about USB HDD backups loading, and learned that backup discs run at 3X speed, original discs run at 6X, while USB backups loading speed exceeeds original discs.
So approximately how fast does USB load ?
Another question, say if a person is playing online (using backup discs) with another person (using USB HDD/original disc), will he/she experience glitches or lag in gameplay, because of different game reading speed ?
Thanks for reading my question :)
