15GB of Google
The news that Google is offering 15GB unified storage on Gmail, Drive and Google+ will please many. I am currently on 31% used, but it looks as though Google will always be ahead of my requirements in this area.
From the Gmail Blog. Life gets a bit easier when your Google products work well together—whether that’s inserting a Drive file into an email or sharing a photo from Drive on Google+. As this experience becomes more seamless, separate storage doesn’t make as much sense anymore. So instead of having 10 GB for Gmail and another 5 GB for Drive and Google+ Photos, you’ll now get 15 GB of unified storage for free to use as you like between Drive, Gmail, and Google+ Photos.
