SD card reader (LeGo)

Hey all, having some stutters, and whenever my game stutters, my cpu and GPU wattage go way down. I don't think it's thermal throttling, as my temps are ok and it only happens for a moment. This is only happening in a few games so far, specifically Palworld, witcher 3, and TF2. Both games are on my SD card. I'm playing on a Legion Go, if that helps.
