newer wii model

so I've recently gotten into modding consoles and I successfully modded my wii, however I have a few questions about how to load up my games. Can someone confirm that i can use a letterbomb with a 128gb.

the follow up question is if the mod is limited to a 32 gb flash drive, is there a way I can keep the 32 gb flash drive for the mods and then load up my games from the 128 gb?

any help would be appreciated
