Google Drive is one of the cheapest cloud storage services, offering users 15 GB of free storage (Google Mail and Google Photo storage are counted toward your limit) and paid storage at rock-bottom prices ($2 per month for 100 GB; $10 per month for 1 TB). Reviewers love Google Drive's powerful search feature, which scans the text of documents as well as file names, and experts also appreciate that changes in collaborative documents appear in real time, as you type.
Functional yet simple interface. Experts say Google Drive's design mimics rival (and our Best Reviewed Cloud Storage) Dropbox's simple, functional interface, which is a good thing. Files you add to the Google Drive folder in your browser or on your computer seamlessly and immediately sync with Google's servers and appear on your other Google Drive-enabled devices within minutes. Google Drive is known for being a virtual service, but just like Dropbox (2 GB free; $10 per month for 100 GB), you can also download a client onto your desktop that lets you edit locally and drag and drop files into your Google Drive folder. Google Drive supports Windows PCs, Macs, and Android and iOS devices.
Up to 30 TB of storage available. Google Drive offers 15 GB of storage free; $2 per month unlocks 100 GB. The plans continue all the way up to 30 TB (Est. $300 per month), which is significantly more than most users (and many businesses) need. If your Google Drive account has a Gmail account associated with it, the Gmail account's storage space will be counted toward the limit. The deep integration with ad-supported Google products raises privacy concerns with some reviewers. For other budget online backup services, try Copy (15 GB free; $10 per month for 250 GB) or MediaFire (up to 50 GB free), which have fewer bells and whistles but work with Windows, Mac and Linux.
CNET's Sarah Mitroff picks Google Drive as a good overall choice and best for Google users in this comparative review of Dropbox, Microsoft OneDrive, Google Drive and Box. Google Drive's third-party apps and editing functions also make it a winner.

Google Drive is awarded 4.5 out of 5 stars (just behind rival Dropbox) thanks to its "generous" 15 GB of free space. Google also offers two-step verification to secure your files, but files are encrypted in the weaker 128-bit AES rather than 256-bit.

The Dropbox-like syncing functionality, excellent collaborative editing abilities and the built-in OCR technology of Google Drive help earn it an Editors' Choice award from PCMag.com. Poor media streaming capabilities knock a point off of its total score, however.
