I've been using the T7 and T9 portable ssd on my steam deck for a year now. It'sthe best way to download and play games on the go. I use the T9 for the deck and now I use T7 for movies and pictures and backup data etc. I'll say transfer of movies on both is a breeze! Transfer like 10 movies weighing about 600mb a piece in a couple of mins.
That usb-c port is insane! I've played Minecraft on it with a keyboard and mouse on an external monitor while charging. I never knew usb-c could do so much at once!
