When you use retro computers and consoles you are familiar with dealing with memory cards. Sometimes preparing those memory cards in your modern computer is way faster and user-friendly than in the system itself. I use a 5.25 USB 2.0 card reader from LogiLink, the UA0341. Be aware it’s mentioned as USB3.0 hub but the card reader is connected via the USB 2.0 header. See the maximum speed of 19 MB/s on the CF Card reader test I did.
