Has anyone *actually* had a problem with cards > 32 gb?

This will help you understand a little better why Wyze previously said they only supported 32GB cards:

Basically, all SDHC cards in FAT32 format were limited to 32GB. SDXC cards (anything above 32GB) came in exFAT format, but exFAT was a proprietary format owned by Microsoft, so it couldn’t legally be supported without paying fees/royalties to Microsoft, while FAT32 could be used for free. Meaning that cards larger than 32GB couldn’t be advertised as being supported (since they all came in exFAT format), though you could reformat larger cards into FAT32 and they would work fine.

It was more of a legal politics type of thing preventing them from saying they supported it before now even though you could basically always use large cards in Wyze cams (sometimes even without reformatting them into FAT32, but reformatting them helped make sure they were more reliable).

Now Wyze has obtained a license to use exFAT, so basically all the microSD cards above 32GB will now natively work in their cams (no special formatting necessary), and they can legally advertise and claim they support greater than 32GB cards.

So supporting exFAT really just means supporting SDXC which really just means they natively support microSD cards the way they came greater than 32GB…but you could always use cards greater than 32GB, sometimes you might’ve had to reformat to FAT32 first, but that is no longer needed now that exFAT is officially supported. Use whatever size MicroSD card you want. The only limit is:

  1. Must be a microSD card
  2. Must be exFAT (or FAT32)
  3. SDHC or SDXC might be a requirement. I don’t know for sure if the upcoming SDUC or SDIO types will make a difference or not.

Currently SDXC exFAT microSD cards should be up to about 1TB in size this year, so that should pretty much be the limit for now…SDXC can go as high as 2TB, so that may be limit for these cams, IDK. If the cams do support SDUC then they’ll theoretically be able to go up 128TB. SDUC does say that the interface can be used with SDHC And SDXC cards, so who knows. But either way, you should at least be able to go up to 2TB with SDXC cards using exFAT format.
