According to TechCrunch, Google has announced that it will be unifying its cloud storage between its products, including GMail, Drive, and Photos (Picasa). Instead of trying to keep track of your storage across your Google products, you’ll now be able to just watch one graph to know when you’re reaching your limit. The free tier for storage will give you 15GB!
If you need more storage, there are purchasing options available as well, which will also be shared across your Google products.
Google says the updates will be rolling out over the next few weeks.
