I have a micromax canvas A117 phone. And i need a 16 Gb ultra class 10 sandisk microsd card for it.problem is that my phone probably do not support uhs-1.so if i install a uhs-1 card in it, i know it will not provide me speed of uhs-1. But i want to know that will it provide me read/write speed of a class 10 or less. Should i go for a non-uhs class 10 card??
In that case where your host device does not support uhs speed then it will work with the class speed of the card that is slower that the uhs bus of the card.
In that case where you cannot use uhs cards then i would suggest to find a non uhs card if still available. Unfortunanelly non of the Sandisk cards have only the class speed.
