1)Google Drive
Google Drive is a cross-platform cloud service.
Advantages:Users are able to start with 15 GB of storage for free, and can set up the program to automatically sync and update files. It also automatically syncs with other Google applications such as Gmail.
Disadvantages: For people who need more storage, Google Drive is no longer a free option. Users can get anywhere from 100 GB for $4.99 per month all the way up to 16 TB for a whopping $800 per month. Also, because it is synced with other Google applications, these also use Google Drive storage, so users who have an enormous amount of files stored in Google Docs or Gmail may also need to upgrade the storage space.

2)Box.com
Box.com is a cloud storage service that offers both free and premium accounts.
Advantages:This site’s free account offers a 10 GB storage space, with a file size limit of 250MB. All accounts are able to be accessed both from the website and from compatible mobile devices. All accounts are kept secure with SSL encryption and a two-part authentication system.
Disadvantages:Like some of the other options mentioned on this list, if the user needs more storage space, then the price tag goes up. Unlike Google Drive, this program charges a monthly price per user. The prices are reasonable, between $5 and $35 per user, but that can add up quickly for larger groups or companies.
