Pros
Pro All your files are automatically synced between every device you use
No matter the device you use - whether it be a different computer, a tablet, or a phone - Google Drive has the ability to sync automatically between many different operating systems, ensuring you have access to your documents anywhere you want.
Pro Extended functionality via apps
Third party Drive applications running in Chrome can add functionality such as image/video editing, project management, flowchart creation, etc.
Pro Password protection not necessary
When sharing, simply use the targeted person's e-mail to share a folder with, and that person will be granted access. Alternatively, you can choose to share by using a link, which you can publish for all to access.
Pro Indexes images
You can search images by object, place, or face when they've been added to your google photos collection. Google Assistant also helps you find screenshots that could be archived, images that aren't in the correct orientation and pictures that would work well as animations or albums.
Cons
Con Your data (files, document, images...) is probably not stored in the country of your choice
There is no way to know and even less to choose where your data is stored, and where it is backed up. So it is possible that all your information is accessible to the NSA, even if you are not a US citizen.
Con Terms and Conditions allow Google to own anything on Google Drive
They can create derivative works, they can perform it, they can modify it, and they can publish it at will. There are many other specific rights they take over your product. Read the Terms carefully and compare with ANY others.
