Last week, Microsoft changed its policies regarding free storage in its OneDrive account. Until last week, customers could enjoy free accounts with up to 30 GB of online storage. Changes now reduce that to 5 GB, even for existing customers.
A few months ago, I recommended Microsoft's OneDrive solution. After these changes, I say stick with Google Drive. The last thing you want to do is become dependent on a service and then have the terms change and get stuck with a large bill.
This action proves that Microsoft simply is not comfortable in the free services business model. Google is and will likely remain so. Google Drive is now clearly the better option and will likely remain so.
