Storing teaching materials as well as students’ evidence in a cloud is one aspect of a very popular concept of paperless classroom. Instead of printing out handouts and worksheets, you can share them easily and fast and with students giving them access to any platform you choose for that purpose. Apart from obvious benefits of saving time and money, storing materials in the cloud encourages sustainability and helps develop a conservationsit mind so important in the 21st century. Although my and my students’ choice is Google Drive, which I describe in a separate post, there are more options worth looking into: 
Like others, it offers online backup and automatic file sync for work files or personal files like photos, videos, and music.
DROPBOX –
Stores up to 2 GB plus you can get 500 Mb for recommending Dropbox to your friends. This way you can earn additional 16GB space.
It starts out with 5GB of free storage space, plus you can earn up to 20GB more space by telling others about Cubby. You can Store, Share and Sync.
SKYDRIVE –
7 GB storage – so far the biggest for free
BOX –
It stores, it syncs beautifully and fast, it gives you options for sharing with different people or for keeping files private. And, apparently, “more than 85 higher education institutions have adopted Box’s cloud collaboration service to help their communities of students, faculty, and staff access, share and manage content online and from mobile devices.”1http://www.marketwire.com/press-release/cloud-goes-school-more-than-85-universities-adopt-box-help-students-faculty-administrators-1744040.htm
