I cannot certify for sure but if many people use 200 GB card, it should be possible for you to use it too.
It is just that some error messages may appear when you connect it to the PC (like "this card is corrupted, do you want to format it ?") but in that case you just skip it by answering No and do what you have to do.
However, you may consider that 200 GB micro SD card are quite expensive compared to 128 GB card (considering the storage / price ratio).
Thank´s!!
They are expensive indeed...
I might go for a 128gb with a standard speed. I think it´s abou 80 MB p/ sec.
