AVfile, I may have misunderstood parts of this but check out the below review and you will see what I mean about USB drives. I now have four 512 gb USB drives and nothing is slow about accessing music. All my USBs are used in the rear. I have two front ones but they cannot be used for whatever reason. Have you ever had this issue? My front USBs have never worked.
