The service is now available for PC, Mac as well as Android smartphones and tablets. But the version for Apple's iOS devices will come later.
Google offers first five gigabytes of storage per account for free and users can choose upgrades from 25 gigabytes for 2.49 U.S. dollars per month to one terabyte a month for 49.99 dollars.
In the blog post, Sundar Pichai, the company's senior vice president, said Google Drive can stand from the already established cloud services for working seamlessly with users' overall Google experience, such as Google Docs, Google+, search and Gmail.
For instance, users can attach photos from Google Drive to their Google+ social network and attach files directly to emails in Gmail.
Cloud storage and collaboration is not new as Apple's iCloud, Microsoft's SkyDrive and Amazon's Cloud Drive, and services from cloud startups like Dropbox and Box have been in the market first.
Some analysts said Google might be late to the cloud game as millions of users have uploaded their files to other services. But others believed that from search, email to web browsers, Google's search engine, Gmail and Chrome all grow to grab a large market share as latecomers.
