    Yeah, my SSD can do somewhere around 7GB/s read/write, barely half that with the encryption enabled.

    And I have an external USB carry with an NVMe drive which should be perfectly capable of doing the maximum (1GB/s on a USB3.1 port) , but with encryption enabled, it’s struggling to do over 350MB/s

      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.
