Does ROG Ally Support MicroSD with Random Read Performance of A2?

[Allen_Barry]

I'm trying to find a MicroSD card for my Asus ROG Ally.  I'm having a hard time figuring out if it supports a Random Read Performance of A2 as described at the end of this article: https://learn.adafruit.com/understanding-microsd-and-sd-cards-speeds-markings-and-more/markings-spee...

Does anyone know if it supports A2? or if I need to find a MicroSD card with A1. The article mentions only specialized hardware supports A2.

Largest A2 MicroSD I could find was 256gb. Between that and the uncertainty if A2 was even compatible, I just went with a 1tb A1 MicroSD card.

I have to admit I didn't give it as much thought as you.  I purchased a 1TB Lexar PLAY microSDXC from Amazon.  It says it's an A2 device and seems to work fine in my Ally.
