A:Answer I found that the only thing you need to worry about is if the device can use the amount of memory.
For example, I found that even though my Tab A is rated for a 512Gb, it won't really accept more than 256Gb.
MyMoto G is supposed to take a 1T Gb card but, was told 512Gb is what it really can use.
All devices have these limits.
A Google search helped my make the decision.
