One of the biggest challenges as a professional photographer these days is managing all of my digital assets … in other words, my photographs. I shoot thousands of frames each year, particularly now that I’m shooting a combination of 35mm and medium format. The amount of hard drive space that I need gets larger every year. Since 2010 I have seen my space requirements increase by at least 50% over each previous year. But having enough space to store all of your current files and archive all of your old ones is only the beginning. Because you don’t simply need space for each one of your files. In reality, you need space for three copies of every single file.
