So you have 600/630 = 95% of the job done. To finish, I suggest rsync starting with this as the destination of the copying. Even if the source data is changing a bit from day-to-day, I'm sure the great bulk of it is static. Keep repeating the rsync update until you get a clean, no descrepancies, run. Switching to a different disk interface standard (and abandoning the existing 95% solution (?) ) makes no sense to me.
