Thanks, appreciated, I measured the 2 cards, and writing speed appears to be the difference. What is it going to be used for? Crypto mining, particularly DeepOnion. It may not make much difference with the writing speed for this. May also run some other staking cryptos in parallel like IFLT and EMB, but one by one.

I have 2 32GB cards, one does 40/20MB/s the other 80/10MB/s, +-, as measured. Both class 10. I understand there are some limits on the SD bus, thus you can not use max speed a card may eventually provide. So my question, which one would be preferred ti be be used? 40/20 or 80/10. Thanks.
