Will simultaneous network connections increase transfer speed?
Use gigabit ethernet, that should be your best bet I think. As for load balancing your connections, first see if you can saturate your gigabit connection first. Even allowing for 10% overhead, that will still be around 115 megabytes per second. I highly doubt that your harddrives (especially the one in your laptop) can read and write that fast, sustained. Your bottleneck is not your link, but the harddrives.
