charts showing each service’s free tier sizes, file size limits, and pricing, as well as some of the perks and drawbacks of each service (via Cloud storage: a pricing and feature guide for consumers)
Pro: Can increase your free storage by 500MB for each friend you invite, one of two services that offers a Linux app, robust mobile apps.
Con: Default storage is dinky compared to other services, paid storage is expensive.
Pro: Integrates with your Google account, has one of the highest max file sizes.
Con: Has one of the looser terms of service/privacy policies, only mobile app is on Android (though iOS app is said to be on the way).
Pro: Has an automatic backup feature for whole devices, though only for iOS devices and certain types of files.
Con: Serious file type and size restrictions, is primarily meant to work with iOS/Mac OS X.
Pro: Largest free tier that may be upgradeable to 25GB depending on if you’re using an old Windows Live/MSN account, only platform that works on Windows Phone so far, second-lowest price per GB per month.
Con: No Mac client if you don’t have OS X Lion installed, mobile clients let you upload only one file or picture at a time.
Pro: Cheapest paid tiers of all the services (though Box charges by the year).
Con: No desktop sync without upgrading to a business license, file size limit tied with iCloud for smallest.
Pro: One of the few services preparing to offer a Windows Phone app (not out yet), no file size limit.
Con: Only more expensive service is Dropbox. Some may say the company is wasting its time supporting Windows Mobile.
Pro: Takes privacy and security the most seriously of all the services, bar none; no file size limit.
Con: Requires install of desktop app to use, default storage size is small, mobile apps have not been well-received.
