I use it to store movies. Commissioning in minutes, regardless of the operating system, Windows XP, Windows 7, Windows 8 and 8.1. delivery respected. In addition to the 2GB we can put in this little box. I recommend this product for reliability that is second to none yet no one is safe from a manufacturing defect. For the first commissioning, plug the supplied cable with her and leave it for 48 hours in operation, after that time, it should work for some years. AMAZON thank you again for competitive pricing.
