Does your laptop have an SD card reader?
No, unfortunately not. Fair white you have to say that he is a good 7 years old.
Yes.
But only use it if I want to flash any images (systems) on a card. I don't want to have it in my new PC, a USB-C connection makes more sense for me.
Yep, if not, there's a USB-SD adapter
Yes but. The part is not used except by customers
Yes, I also use it to read my camera's memory card.
