For a nomadic sharing very easy but slow

This small hard drive, 64GB, which is not nothing, loads easily via the micro USB port on the computer. You drag movies, music or photos of a drag move in the explorer. I also used a memory card for sharing photos in real time with friends.
At this level, no worries.

However, for sharing, use the SanDisk application on the phone or on the shelf. Impractical, the application connects to the hard drive of the network (so it is no longer on the classic wireless). In short, it is long loading for photos but found there. In contrast with iphone, can not easily detect the videos (and know what they cover). It's a little long, it oar a little.

I can not imagine car use for children watching two different movies on their tablet. I think the application is improved.

Battery level, nothing to say, the disc holds up to several hours without a problem.
