OneDrive is free online storage that comes with your Microsoft account. It’s like an extra hard drive that’s available from any of the devices you use. You no longer need to email files to yourself or carry around (and possibly lose) a USB flash drive. Instead, whether you’re on your laptop and working on a presentation, viewing photos from your last family vacation on your new tablet, or on your phone reviewing your shopping list, you can get to your files in OneDrive.
Dropbox is an easy, secure way to access to your files from anywhere in the world. Set up an account and get 2GB of free storage. You can also pay for more storage, if needed (up to 100GB). 2GB not quite enough, but don't want to pay? Invite your friends and for every person that joins get an additional 500MB of storage added to your account. (Up to a total of 16GB) Dropbox has compatible apps for iPhone, iPad, Android, Blackberry, Windows, Linux, and Mac OS X. Dropbox also offers online access to your files without downloading an app. Accidentally delete a file? Not a problem!
Dropbox keeps a history of all your work and will allow you to restore any files or settings to the way they previously were. Dropbox also secures your data over an encrypted channel, so your data is safe! Dropbox is like having a thumb drive with you at all times without actually carrying it.
