title: Fastest way to download large files from AWS EC2 EBS
body: <p>Suppose I have a couple of terabytes worth of data files that have accumulated on an EC2 instance's block storage.</p>
  
  <p>What would be the most efficient way of downloading them to a local machine? <code>scp</code>? <code>ftp</code>? <code>nfs</code>? <code>http</code>? <code>rsync</code>? Going through an intermediate <code>s3</code> bucket? Torrent via multiple machines? Any special tools or scripts out there for this particular problem?</p>
