Sure, let me mount this up with a FTP drive, and fill data up. Never order nor get services from any company, ANY, if they advertise unlimited everything.
The catch with this service is show in that little screenshot of the plan name, and its components. Take a special look at Innodes used, and hits used.
Instead of counting the storage and bandwidth use, they will count the amount of files (innodes) and the visits/hits to your site (daily hits). This seems a shitter way of limiting the end user. Mind that, 50k hits is not a lot, but will restrict you plenty in growth. Once you get a big site going, or even forum, those innodes will count up.
I'd move to something more static to count up growth, rather than this.
