title: Fastest way to transfer files between two adjacent computers
body: <p>I have two adjacent computers, both running a recent version of Ubuntu. Both computers have:</p>
  
  <ul>
  <li>Multiple USB 2.0 ports</li>
  <li>RJ-45 connection</li>
  <li>5400RPM hard drive</li>
  <li>Express Card card slot</li>
  <li>PCMCIA Type II </li>
  </ul>
  
  <p>I want to transfer as much data as possible in a set period of time.</p>
  
  <ol>
  <li><p>What is the fastest <em>physical</em> medium to transfer data between the two computers without swapping hard drives?</p></li>
  <li><p>What is the fastest protocol (not necessarily TCP/IP based) for transferring high-entropy data? If it is TCP/IP, what needs to be tweaked for optimal performance?</p></li>
  </ol>
