Hi- I want to use the new Tab 7 for video production, and to backup/ transfer SD card footage (Sony A7R2) to external HD- at the USB 3.1 speed. Will this be possible? It will be easier to travel without laptop- I did try to use my Samsung S9 plus phone for this, and could copy/ paste to the internal microsd card, but not a straight transfer to Seagate 3.0 HD. Any advice?
