25mbps actual throughput isn't all that bad over your home power lines, obviously not spectacular but enough for streaming video for sure. I can usually stream HD netflix on 20mbps on my home internet connection. You're right though, hard wired cat5 with a decent switch would def be at least 10x the speed.

Rough calculation here: 30 GB = 30,000 mByte = 240,000 mbit / 25 mbps = 9600 seconds = 2hr 40min to copy file, if you get max speed the entire time with nothing else using network bandwidth. That's a long time to copy 30GB, when you hard drive could do it in a few minutes over gigabit ethernet.
