I use a 64 G SD class 10 to store my raw images(24mp) and a 32G Jpg on my D610.
If I plan to take a trip and do not want to carry two many chips, can I use this unknown brand 256G mSD which sells at $16

I understand the risk could be too many eggs in one basket.
I would like to hear your experience of using mSD on camera and this kind of 256G mSD .
I think using mSD chips has an advantage, which can be just inserted into your smartphone or tablet and view them; then I just need 1 256G and 1 16G mSD for my trip.
