I have no idea what this is, but it seems interesting! Something about storage. Possibly not for the normal individual at all. Possibly only for companies, or for those with paid plans (those with paid Google Drive upgrades will apparently be getting upgraded early).
I stumbled upon this today while browsing through Google's ever-expanding array of often useful and so very functional products.
You can sign up for early updates right here if you like.
UPD: Some more info here, though it seems to still be a work in progress... basically: a little bit more of everything. A bit cheaper. A bit better. A bit more of an incentive-based Google experience.
