Previously, we had our movies, music, photos scattered on multiple external hard drives. We had to every time find the right hard disk to find what we wanted. But that cétait before. Now that we have the DS115J associated with an internal hard drive WD Green 3TB, everyone has access to movies, TV shows, mp3, pictures from his tablet, laptop or mobile phone. A delight for the whole family. For added security, we have programmed there a backup of our photos (it didnt !! price) on a external hard drives we were using. In short, no complaints yet.
