What are the benefits of advanced techniques to optimise data transfers? Researchers from Italy and The Netherlands have come out with a set of benchmarks that allowed them to compare Dropbox, CloudDrive, SkyDrive and Google Drive. Which is the best? You can check it by yourself by running the tests on your own if you like."
What this kind of benchmarking can't well do, though, is predict which of these cloud storage companies are going to be around in five years, which might be at least as an important a factor.
