I have created nearly all of my documents and many of my presentations in the same Google Drive account for the last six or seven years and I have yet to run out of storage space. But if you store a lot of large multimedia files in your Google Drive account, you might bump up against a limit. Starting this week Google Apps for Education users will not have to worry about storage limitations again. Yesterday, Google announced that Google Apps for Education users will now have unlimited storage space for free.
In that same announcement we learned that by the end of the year Google will begin providing Google Apps Vault for free to schools using Google Apps for Education. Google Apps Vault provides administrators with email and chat archiving, drive file search, email search, audit reports, and tools to comply with legal hold requirements.
