Google is set to take on Dropbox with a full cloud storage service called Google Drive, which according to leaks will launch sometime this week. The service will offer 5GB of storage for all users for free – this compares to Dropbox’s 2GB – promising users this: “Put files in Google Drive, and you can access them on your desktop, mobile phone or tablet, anddrive.google.com“. Changes made to a file on one device will be reflected on the others, and if users want more than 5GB of space, they can pay to upgrade. Google already has separate cloud services for music, documents and other content, of course. It will be interesting to see what kind of sharing features Google Drive allows though.
