According to tests (2 programs from different developers) and actual use, the write speed is maximum (!) 19Mb / s with a read speed of 130Mb / s. I don't know how it turns out. Tested on USB 3.0 (external HDD writes 60-90Mb/s). On USB 2.0, the read speed drops, the write speed remains the same. I don't know how this is possible.
