What are the best options for online storage? Is there service people can recommend for around 100gb of storage? (Not a full backup service, just storage)
If you subscribe to MS-365, you'll have access to the latest version of the full Microsoft suite plus 1,000 GB of storage for $99/yr, or else pay $129/yr and a family of 6 get the Microsoft suite plus 6,000 GB of storage using OneDrive. I reckon the family deal is pretty good value.
Box is what we use at work and is more professional with great version tracking and access control.
I have 1 terabyte of storage through work's Office 365 subscription. OneDrive is an excellent product. I'd be tempted to pay for OneDrive myself if i left work and it cost around $100 a year.
