Questions about this item

Does the UHS-I interface on this card limit real-world read speed to 80 MB/s?

Yes, the UHS-I bus caps sequential read at 80 MB/s, and the card is rated for that maximum.

What physical slot does the SDSQUAR-128G-GN6MN require?

It fits any microSDXC slot; the card measures standard microSD dimensions and no adapter is included.

How is the A1-rated card set up on Android, and what step is often missed?

Insert the card, then format it as internal storage in Settings so apps can be moved to it; skipping that step leaves the card as portable storage only.
