Ahead of its I/O event this week, Google is performing some quick spring cleaning—the good kind!—by unifying Gmail, Drive and photo storage into one lump sum. Moving forward, instead of having 10GB for Gmail and 5GB for Drive and Picasa / Google+ photos, the search giant has combined the two so you have more storage for the stuff you want, whether it's documents or those new headshots of yours. The added space will be highly convenient, particularly for anyone with large video files. 15GB, incidentally, is quite a bit of free storage right off the bat, meaning your Drive account is a pretty competitive option against the likes of Dropbox.

With the addition of unified storage, however, Google is getting rid of the option to add 25GB of storage to Drive for $2.49/month. You can add 100GB for $4.99/month, or 200GB for $9.99/month. If you're not a heavy Gmail user, you can do as you wish with the 15GB of space, or vice versa; it's up to you. These changes are expected to roll out over the next couple of weeks so you should see the unified storage fairly soon.
