I am a professional photographer that works from home. I trying to figure out the best set up for file storage. Currently I have an early 08 Mac Pro that has two 2tb drives in it. they are dedicated for file storage. I also have external drives that I back-up all of the internal drives too. Here's the problem, those drives are full! Now I'm trying to figure out what the best option is. I don't have a lot of space to set up a rack/stack server in my office. I have looked at the Western Digital 8TB (Sharespace), and think this could be my best option. Obviously I would have to get 2 of the so I can set up a back-up. Do I have any other options?
