100GB of free cloud storage, the catch is that you have to give up 150gb of your own space and share it. It's an ideal solution for me, I needed a good 20-30gb of space for free, and can easily give up the 150gb and a bit of my new fibre connection. the client has fairly simple setup for bandwidth limits and different times of day. Worth a try if you need more cloud storage than most places offer, and don't want to pay for it!
