@colstar yeah that's understandable if you are new to this. My point is you don't even have to use a UBS stick to transfer ROMs. Can do it all with your PC and its not even a very technical process. But if you like the USB way that's cool
It was more a generic question about the lifecycle of an SD card if it's in a Pi as there always seems to be stuff being written even when idle.
Things get written to logs when events happen - it's not an issue to cause excessive write tearing. Unless you have a problem which gets logged continuously in the logs (such as under-voltage warnings), the normal operation on a Pi will not negatiely impact the negatively the sdcard lifetime.
You could configure logging to RAM instead of persistent storage (with something like Log4Ram) if you wish.
@djshenanigans You can use the File Manager (from the RetroPie system in EmulationStation) to copy your ROMs to the SD card, from the USB stick. Just rename the retropie-mount folder on the USB, so it's not automatically mounted over the ROMs folder by RetroPie. After plugging in the USB stick, the files there should be available under /media/usb0.
@mitu Cool! Thanks a million for that I appericiate it. Yeah the wonder of Chineseum arcade controller sets from Amazon... every time the keyboard encoders are ever so slightly different with some showing as something like Micronek (Microtek) and some as Dragon something.
