Google Drive—a place where you can create, share, collaborate, and keep all of your stuff. You can upload and access all of your files, including videos, photos, Google Docs, PDFs and beyond. Google has integrated all its existing technology and apps into Google Drive. You can install Drive on your Mac or PC and can download the Drive app to your Android phone or tablet. A Drive app will soon be available on iOS devices. I am baffled that they have left out Linux. Blind users can access Drive with a screen reader. Google Drive lets you search for files with a variety of filters. The best part is, it has OCR (Optical character recognition) built into it, which means searching your scanned documents will be much easier.

Currently Google Drive offers 5GB of storage for free. You can choose to upgrade to 25GB for $2.49/month, 100GB for $4.99/month or even 1TB for $49.99/month. When you upgrade to a paid account, your Gmail account storage will also expand to 25GB.
