Google Drive is not yet available in Google Apps @ NC State. NC State is on the “scheduled release track,” which means that OIT gets a little extra time to test and document new releases from Google before they are available to our users. This is to ensure that brand new offerings from Google do not impact the Google Apps @ NC State service.
According to estimates by Google, Google Drive will be available to scheduled release schools some time in the 3rd quarter of 2012 (July/August/September). More information about Google Drive on Google Apps @ NC State.
