We’ve heard of Google Drive a few times over the past few years. The service has been real in the past and was used internally, but due to problems and it not being ready, it never made it public. This could be changing soon.
GDrive is a service that is similar to Google Docs in that you can store documents and files within the cloud. What GDrive will do is make it more noticeable to all users that they can store more than just the documents they edit within the cloud.
