BOX

This service is more of a business-collaboration and work-flow solution than a storage service. If that's what you want, it's well worth considering. For example, the business editions of Box come with robust permission options that lets you call the shots on who can view and edit various files.

In addition, the business versions of Box include access to a variety of work programs, which are integrated with Box's cloud storage and services. These include Box OneCloud, for improved mobile work-flow, and Online Workspaces. There are also a variety of business-specific apps.

Box's basic free version offers 5GB of free storage. You can sync files between your Windows/Mac PCs and the cloud, and vice-versa with the Box Sync program. Box also supports Android and iOS devices. It does not, however, integrate with your file systems.

The personal editions also offer 25GB for $9.99 a month and 50GB for $19.99. Business edition starts at $15 a month for a whopping 1,000GB of storage.

If you have a use for its business applications, Box may be just what you want, but it wouldn't be my first choice for personal storage.
