Google Drive

Google Drive is a free storage service that gives users 5GB of space. Users can create new documents, spreadsheets and presentations instantly - just like with Google Docs - and work together at the same time, on the same doc, and see changes as they appear. This is a wonderful offering from the search giant and it directly competes with DropBox, Box, Microsoft Live, iCloud, and others. For schools using Google Apps, this is a clear choice for students and teachers.
