I like that Raysync provides an easy interface between my desktop applications and cloud storage services such as Google Drive and Dropbox. It's very simple to use once set up correctly. The only thing about this service I dislike was having to pay money every month when using their free version. If your looking into transferring lots of data from one computer/device to another then raysyc should be considered! Transferring multiple GBs of photos, music etc without worrying if there will be enough space left in our dropbox account.
