I use mine exclusively for emulation and ROMs, entire libraries of every single game released for older systems. The SD card I have for that runs them fine without issue. Potentially with newer/bigger games you might come across issues, that I haven’t really done at all.

How many different game are you trying to play at a time?

I’ve been using a 1tb sd card with mine and my steam library. Not any noticeable difference in speed between the internal ssd and micro sd.
