When it comes to the free cloud storage, Google Drive is the most generous one. You get free 15 GB of Google Drive, no referral or any other trick needed. Google Drive storage is shared by GMail and Google+ Photos, but you should know that photos smaller than 2048×2048 will not count against your storage, and Google Docs, Sheets, and Slides do not use your storage either, so if you can keep your photos within the limit aforementioned, then you can store unlimited photos in Google+ Photos without costing you a penny.
But sometimes I become a little bit greedy and wish I could get more free Google Drive storage, and lucky me when I stumbled on a Google Drive post talking about Safer Internet Day. Obviously, Google encourages all account holders to perform a short account security checkup, but the part that attracted my attention is that Google will give free 2 GB of Google Drive bonus storage for anyone who completes the security checkup by February 17th, 2015. This is apparently a limited-time offer, so if you want to add an extra 2 GB to your Google Drive for free (who doesn’t?), then you need to act now. At the end of the checkup, you should see a screen as below:
Recently, Microsoft gives away free 100 GB of OneDrive storage to Bing Rewards members, but the free storage is good only for two years. The Google Drive bonus storage is much less than Microsoft’s offer, but it is permanent for you to keep. If you have completed the security checkup, then you can expect to receive the bonus storage around February 28, according to the Google Drive post.
