I was considering switching over to Microsoft’s OneDrive because they give me one free terabyte with my annual office subscription. The OneDrive functionality is already baked right into Windows 8.1 so I decided to investigate further. For me, as a website developer OneDrive will not work for me because it does not support file revisions. Meaning if I have a file open in Photoshop and make lots of edits and saves throughout the day as I’m working on it: Dropbox will allow me to roll back to any of the previous versions made within the last 30 days. Side note: I’m not sure if the collective file size of all of those previous versions counts against my drive space allowance. Either way I’m happy.

I don’t think Google drive supports versioning either.
