Google on Tuesday unveiled its new “Google Drive” cloud storage solution, taking direct aim at Microsoft’s SkyDrive, Dropbox and other similar services. The new offering includes 5GB of free cloud-based storage and allows users to store, collaborate on, and share documents and other files. At the same time as its new Google Drive service was rolling out across the Web, Google also quietly gave Gmail users a capacity boost of more than 35% according to reports. Gmail launched in 2004 with 1GB of free storage and that figure has been increasing steadily to just over 7GB as of earlier this week. On Tuesday, Gmail’s free storage climbed to 10GB according to a report from Engadget. We haven’t seen the storage boost hit our inboxes yet, but a number of users reportedly have. Google has not formally announced the update.
