We just added terabyte #6 to the "stable" of hard drives here at MNP. For those of you that aren't photographers or nerds, a terabyte is 1000 gigabytes. All together we have about 8.5tb of total storage and its seems to grow by a couple of terabytes every few months. We've shot about 2.5tb of images in the past year and we have everything backed up twice on hard disk and also on DVD. I've done tons of research on the best way to store images and the concensus seems to be this way... lots of drives, a second backup of the images on another physical drive and a third on DVD or CD.
When I was first starting out I searched and searched for answers to my questions and although I found a lot of photography related help, answers to questions about storage, workflow and just the day to day business of being a photographer, were not as readily available. Now I'm getting questions from other photographers just starting out about issues they're facing so I thought I'd start posting about stuff like this in hopes to possibly help someone out.
Let me know if you have any other questions!
