Very inconvenient design, to insert into the connector you need to hold the middle part, the frame is not fixed. It heats up like an iron, you can burn yourself. Writes and reads relatively quickly, taking into account work via USB2.0, via USB3.0 it will probably be faster. It starts writing at a speed of about 60MB / sec, after a minute the speed drops to 13 MB / sec, and so on until the end of the recording. The picture is the same with reading.
