I'm not sure which is the problem, reading or writing, but I'm assuming Minecraft is doing both.
To clarify, I'm pretty sure Minecraft does a lot of SD card access while running, and I haven't had corruption issues so far on ofw.
No official applications are allowed to write to the SD card. All savegame data is written to the emmc USER partition, which is formatted as fat32I'm not sure which is the problem, reading or writing, but I'm assuming Minecraft is doing both.

What about minecraft? I'm pretty sure that game is reading/writing to sd, no?
AFAIK exFat has file access time attribute and its constantly updates even if apps only reads files from SD. that's why folder records are open with write access on exfat.
FAT32 has no such attribute and SD in FAT32 is true read-only.
It is the safest option. With USB installs, 4GB+ files are not even a thing, because Nintendo Switch breaks down the installs into pieces meant for Fat32. Unless you are loading blue-ray rips that are at a resolution too high for the Switch to handle, there is no point. Exfat doesn't offer any benefit. Only more risk. The whole point of Exfat is to handle 4+ GB files, and if you are installing NSPs via USB, then you don't have to worry about it. It's just stupid that this is even a topic.so FAT32 is the best option for my new 400gb card?
Switch not breaks file into pieces.
It just uses custom FS to support big files.
As LFN was added to standard FAT as extra records as nintendo extends FAT for 4Gb+ files: it uses several records for this. One folder record with archive attibute and 1+ file records for file chunks.
It is only windows that sees this as separate files. FS driver in the HOS shows this as a single large FILE, not folder.
Just did some quick tests with python and fuse: it is very easy to write custom fs diver for linux, that will see this nintendo specific big files.
I'm using an old version of Atmosphere and Retroarch and was about to upgrade to the new Kosmos version.
I was in the process of copying everything to a new microSD card. When all of a sudden the copying process stopped for two save state files, giving me this error;

So I would play safe as I am doing right now and correctly formatting it into FAT32. I did not knew this. And just Googled this to see the discussion about this.
My feeling is there is a small risk using Exfat concerning corruption, obviously.
I haven't got any file over 4 GB because I only use homebrew and have all my games original as a game card.
I think it really depends on what you want with your Switch.
Yeah these are minor corruptions that can also happen while being on exfat. It doesn't corrupt your whole card but you will notice that some of the files can no longer be moved or deleted.I'm using an old version of Atmosphere and Retroarch and was about to upgrade to the new Kosmos version.

I use a 200gb card, I can't use fat32, But I have NO ISSUE
It is true that FAT32 has a max Filesystem size of 32GB, but Most modern OS's can work around this limitation and allow 2TB partitions in FAT32. I have a 256GB SDCard formatted as FAT32 that works as intended in my switch - Almost filled with Games tooI use a 200gb card, I can't use fat32, But I have NO ISSUE
That's not a filesystem limitation, it's a "microsoft locking it off to force you to use their newer filesystems" thingIt is true that FAT32 has a max Filesystem size of 32GB, but Most modern OS's can work around this limitation and allow 2TB partitions in FAT32.
