That's pretty neat. It sounds like a high school report, or is it not? I used to work at netapp, the team I was on was the one writing the server-software for their cloud servers.
Anywho a few points you may want to touch on...
1) As Laser said, the data is kept safe on remote servers but this can also be a negative. It requires the user to have an internet connection in order to access their data and there's always an off chance that the server could be down or crash. So remember to discuss that.
2) The network's infrastructure is scalable(software side allowing)
3) Cost effective. A Dropbox user is guaranteed 2GB of storage but that data is allocated on demand, not all at once...
4) Ease of use for the general public
That's all I can think of
