Went from a SanDisk 1TB Ultra to a SanDisk 1.5TB Ultra. I just install too many games. I think I have close to 150+ games on my Switch. Do I play them all? Nope! Lol. I just keep them on there, just in case, you know? With the upgrade to 1.5TB, I now have around 470 GB free. So it's a little overkill now lol, but I could load it up with more games that will probably just sit there as well lolWhich capacity microSD card did you use? Previously, I had a 256GB microSD in my Switch v1 that is Kingston branded. Never had any problems so far in terms of partitioning the card or running out of space. 256GB is about the minimum requirement for EmuNAND, and it was the cheapest that I could get; however, it's best to go with something higher like 512GB or 1TB as you had mentioned if you want to install a whole lot of games.
An emuMMC/emuNAND partition is around 32GB, then a separate NAND backup as a file (which is required for restoring in-case of a brick) also 32GB, which in total uses up about 64GB of space on the card. This can be quite problematic with 128GB or lower cards which will tell you that Hekake failed to create it because of insufficient space.
Now my wife has a SanDisk 400GB Ultra microSD card, and now that's overkill for her. She has like 4 games on it. BotW, TotK, Pokemon Scarlet, and Rune Factory 5. So yeah, for some people 256GB is enough.
Realistically, I could downgrade to a 256GB and just play the games I do tend to boot up most often, but I prefer the convenience of knowing that I could play any of the other games I have when super bored.
