The real change is that OneDrive users will be able to earn additional storage in a similar way to Dropbox users. Microsoft is introducing a referral bonus of up to 5GB, which is made up of 500MB for each friend you refer to OneDrive, up to a maximum of 10 friends. OneDrive users will receive the free storage for referrals, and friends who sign up to the service will also get 500MB each. You can also earn 3GB of free storage by enabling the camera backup feature in Windows Phone or the iOS and Android apps. In total, OneDrive will offer up to 8GB of additional cloud storage on top of the 7GB free default allocation. If that’s not enough storage then Microsoft is also introducing monthly payment plans for OneDrive to boost the overall storage.
