The transfer is fast, it's USB 3 and it shows.
It was very easy to carry in another person by simply putting it in my coat pocket.
So far I have had no worries, no errors in the backup .. even if it is still early to know.
Finally supplied software, it can be useful, but it does not serve me. And some are free but paying for the "real" functions (such as emergency backup function).
Negative point: there is no software to pause the device after a certain idle time.
