I have a laptop with USB 3.0 jack, but my USB connecting cables were already old, and therefore 2.0. I tested this model. I made a copy of my hard drive (I'm on Windows 7 that lets you create a backup image). The result speaks for itself. For 130 G0 to save, I need an hour and a half. With this cable Amazon Basics, 25 minutes to do the backup were enough. No comments! I would add that it is of robustness. Conclusion: a very good investment to make for a low price. Highly recommended purchase.
