Google finally announced that it is finally combining the storage of all its cloud and web services - Google Drive, Gmail, Google+, photos - to give an unified experience to the users. This is what was found in the official 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.
With this new combined storage space, you won’t have to worry about how much you’re storing and where. For example, maybe you’re a heavy Gmail user but light on photos, or perhaps you were bumping up against your Drive storage limit but were only using 2 GB in Gmail. Now it doesn’t matter, because you can use your storage the way you want.
We’ll also be making updates to the Google Drive storage page, so you can better understand how you’re using storage space. Simply hover over the pie chart to see a breakdown of your storage use across Drive, Gmail, and Google+ Photos. And if you need more storage, this is your place to upgrade, with plans starting at $4.99/month for 100 GB.
Pro tip: This change means you’re no longer limited to a 25 GB upgrade in Gmail—any additional storage you purchase now applies there, too.
These changes to Google Drive storage will roll out over the next couple of weeks. Google Apps users will also be getting shared storage, so visit the enterprise blog to learn more.
