It’s 32gb internal and iirc they take sdxc micro SD cards. So that’s anything up to 2TB if you’re nuts enough to pay for that. I find 128 - 256 is more than fine. I can always redownload games if I need to.
If you get a family online sub ( imo worth it if you have family and friends with switches as it can work out dirt cheap per person; I think you can have 8 people on a family sub) then you have cloud saves too.
