title: voldemort vs. couchdb
body: <p>I am trying to decide whether to use voldemort or couchdb for an upcoming healthcare project.  I want a storage system that has high availability , fault tolerance, and can scale for the massive amounts of data being thrown at it.  </p>
  
  <p>What is the pros/cons of each?</p>
  
  <p>Thanks</p>
