Google Drive is, well...why don't I let google explain...
Store everything safely and access it anywhere (especially while on the go). All your stuff is just... there. You can access your stuff from anywhere—on the web, in your home, at the office, while running errands and from all of your devices.
Hey, that sounds like cloud networking to me. Google is boosting that Google Drive is even equipped with OCR (optical character recognition), so you can scan a newspaper article and then later search it using a keyword.
Right now, google is giving away 5GB of free storage, which is plenty for someone like me...but if someone needs more, for a small fee he/she can increase the storage capacity.
