Google drive is new entry in world of cloud storage offering. Since it is from Google, people have lot of expectations from this service which is free online storage of 5Gb. More comes for a small price. Right now it is not immediately setup for you and may take a day or two for it to be setup. I tried mine yesterday and it is setup this morning.
Here is a comparison of free drives available on cloud:
HOW MUCH FREE SPACE DO YOU GET?
Amazon Cloud Drive: 5GB
Google Drive: 5GB
WHAT IS THE LARGEST FILE YOU CAN UPLOAD?
Dropbox: 300MB on website; no limit on desktop
Amazon Cloud Drive: 2GB
Google Drive: 10GB
So it is clear that Google wins as far as large files are concerned. They allow more than 30 types of files to be uploaded and shared with any one.
Great going Google! Keep it up.
