Dropbox has been the go-to storage choice for many years, and gives you 2GB free – after that you need to upgrade to the Pro version, which offers a flat 1TB of storage (oddly, no other options are available). The interface enables you to drag-and-drop the files you want to store online into a Dropbox folder on your machine. These are automatically synced to the cloud; if you delete one from your computer, the files are also removed from the server.
Files can also be uploaded via a browser, and you can set up the online folder structure in any way you like. Once the files are in place they can be easily shared. Using the mobile app is equally easy and enables you to preview, download and share your files. Although Dropbox doesn’t offer a dedicated imaging application, the simple folder structure will appeal to those who like to have full control over the way their files are stored and organized.

Pros: Easy to organize and maintain your files
Cons: Workflow seems dated
We say: Well-integrated with both Mac and PC systems – one for those who like to have full control
