I wonder if Xbox (Microsoft) would consider making a large capacity network storage unit either it be a fixed high capacity or a docking station to plug any size new hard drives into it. If they can get people to store to cloud I am sure they could make a Xbox network capable to share data within a network.
Also if they would like it to be connected to the Xbox itself why not add a USB 3 port (In new models) and allow the multiple hard drive solution to plug in more than one 250GB or 320GB.
We as users need to get Microsoft to provide us a good storage solution, always running short on storage is a pain.
Let me know if you agree
