OneDrive is much better than the Dropbox, Onedrive give you Unlimited space with Office 365 for $70 year
I am a professional photographer and use dropbox to store my completed photoshoots. I do not have other users it is just myself and I have nearly filled up the 3TB limit. I wish their was an unlimited option for individuals as you currently need to purchase 3 licences for the unlimited storage option and I only need the 1.
Thanks
