Just wanted to start a thread where people could post knowledge and experience. As we all know the 950 XL will work with the largest capacity cards available today. The problem though is those high capacity cards tend to be relatively slow to write to. I know with cameras this can present problems when recording 4k movies or doing burst mode photography. Having said that the write speed of the card is not the only factor. The other major concern is how fast the device itself can output the data to be written. It is not at all clear that the 950 XL is capable of taking advantage of the super fast cards. I have a Sandisk Extreme 64 GB microSD card in my 1520. Does the extra write speed capacity help? I don't know. There is no way to directly measure the phone's write speed.
If anyone has any light to shed on this issue please post.
