Nope, network is basically the only way. You should get well over 100mb/s for an interface aggregate with both onboard ports.
But don't SCP then through the service console as it is painfully slow. If you use NFS as datastore, you can copy them from any linux box via NFS mount. If you have to use SSH through the Service Console (for FCP LUNs for example), use some tool like Veeam FastSCP or similar, as it is a lot faster than regular SCP.
