@truglodite said in How can I boot RetroPie from NVMe or SSD (without SD)?:
I am guessing retropie still will write heavily to the sd card despite roms being on an external, correct? Not sure if sd wear is a big deal with retropie, so figured I'd ask if it was and if there's a similar way to mitigate.
Not really, gaming is not a write-heavy process. Game saves and save states are written to the ROM's folder by default and unpacking .zip ROMs is usually done in RAM.
There is no constant write load using RetroPie, like a monitoring/data collection/aggregation process entails, so a good sdcard and proper power source is usually enough.
