If you're all so concerned about storage then why don't you get a WiFi NAS drive... I run a 3TB personal cloud system - it's all under my control with no worrying about other people controlling my data- and I can access it happily from my computers, Nexus, iPad and Galaxy at home or anywhere I can get WiFi or use my Galaxy as a mobile hotspot... 3TB seems to be enough for the moment and it also acts as a backup for data on other drives.
