There are lots of other options you can compare price with - the obvious one being cheap VPSes: BuyVM (happy user) offer 250G for $7.50/mo ($90/yr) or 1TB for $29.95/mo ($360/yr), with the advantage being that this gets you your own IP address and you can run whatever you like on the machine (web server, sftp server, rtorrent, ...). It's not a complete solution for the non-technical, and not vertically integrated like GDrive, but you could probably compete with Microsoft and Google in your spare time with a little margin by reselling them pre-configured: There's ftpfs for linux and no end of ftp apps for whatever phone you've got. I am a huge fan of using cheap VPSes for everything.
