In commemoration of Google Drive finally launching, Google has decided to provide more space for Gmail users. Even though very few individuals are reaching the current, free threshold of 7.5GB, Google has now upgraded the free storage space to 10GB.
In the next couple of days, Gmail users will see their total storage space increase from 7.5GB to 10GB. In addition, you may want to be on the look out for Google Drive, which is scheduled to begin rolling out to Google users starting today.
