UHS-II MicroSD

[Hermes Hidayat]

So i have this SanDisk 128GB Extreme Pro UHS-II U3 MicroSD(rated at 275mbps read and 100mbps write) and i was wondering if it works better or the same as the SanDisk 256GB Ultra UHS-l U1 MicroSD.

There are 2 connectors on the UHS-II MicroSD.

I couldn't find the specs of the MicroSD reader in the Galaxy S20, however I doubt it supports UHS-II at full speed.

Most likely, the card will still work but at UHS-I speed.
