    That seems odd. You'd expect that if the cpu is doing the encryption and can do 3GB/s for the internal disk then it can do the same for the external one and be limited by the USB or disk speed of 1 GB/s

      If it’s a Mac then it’s not the CPU that’s doing the encryption for the internal drive. Macs have separate hardware for that, the CPU can’t even get the key.
