title: Store files on disk or MongoDB
body: <p>I am creating a mongodb/nodejs blogging system (similar to wordpress).</p>
  
  <p>I currently have the images being saved on the disk and a pointer being placed in mongo. I was wondering since I have all sessions being stored in MongoDB to enable easy load balancing across servers, would storing the actual files in Mongo also be a smart idea for easy multiserver setups and/or performance gains.</p>
  
  <p>If everything is stored in a DB, you can simply spawn more web servers and/or mongo replications to scale horizontally </p>
  
  <p>Opinions?</p>
