Modern devices no longer need a crossover cable to directly connect via an ethernet cable. But are there any advantages of using a crossover cable anyway? For example, does a crossover cable decrease power consumption, increase transfer speed, or decrease load on the adapter or other components?

In my example I'm using a cat 6 ethernet cable to directly connect two Ubuntu server machines, and I'm executing data transfers that nearly max out the connection bandwidth.

    At this point, the main purpose of crossover cables seems to be to cause frustration when you accidentally use them for something other than ethernet. – Gordon Davisson Mar 29 at 2:33

"does a crossover cable decrease power consumption, increase transfer speed, or decrease load on the adapter or other components?"

No, not at all. The speed, power consumption, latency, etc. are all the same for a straight-through vs. a crossover cable. The bandwidth is the bandwidth. For 1000Base-T (1 Gbps on UTP) it is always 1 Gbps.
