Question about Sony Xperia 5 II

I would pay less attention to the speed class UHS-* and more to the application performance class A1 or A2.

The speed classes only guarantee pure throughput, which is good for video cameras, for example. For smartphones, with many random accesses from different apps active at the same time, the classes are not very meaningful. In my opinion, you can't go far wrong with A1, and there are no really slow cards in this category anyway.

For example, I once had an SDXC that fulfilled UHS-I V30, but no application class. As soon as it was used in the smartphone, the device became practically unusable. Apps started 10× slower, music interrupted every few seconds, saving a single photo took 30 seconds, and so on.

Thank you very much for pointing this out. A correction request has just been sent.

Müsste in eurer Spezifikation eigentlich microSDXC heissen... https://www.sony.de/electronic...
