I finally tested it extensively and I'm tired of it. Again and again I pretended to have a badly copied picture or a weak power supply. The Zheino mSATA I use works fine over USB, but EVERY time I use it connected through this X850 expansion card I have a few minutes of work before the system ALWAYS crashes resulting in filesystem corruption. Again, note that Pi3 B+ and Zheino mSATA card work fine as long as Geekworm X850 V3.0 USB3.0 card is NOT used. I lost $28 to these guys and I can't afford it anymore.
