Well anything above 12 Megabytes/second is going to go to waste for your case anyhow. Max theoretical for 100Mbit / fast ethernet is 12 Megabytes / second. You will never see that *ever*. Still, I've booted from USB over the host port and I am getting 10.6 MB/s. This is even with an old PATA<->USB 2.0 with no features according to hdparm.
Also, you do not need a hub. Using an external powered hard drive case would work fine. I'd also imagine the hub is slowing things down some for you. I am also using one of RCN's Kernels . . .
