Questions about this item

Does my device need a UHS-I slot to use this card?

Yes, the card uses the UHS-I interface, so the host device must provide a UHS-I compatible microSDXC slot to achieve the rated speeds.

Will this card work in an older device that only supports UHS speed class U1?

The card is backward compatible with UHS-I hosts that support U1, but write speeds will be limited to the host's lower class rating.

How can I verify the card delivers the advertised 200MB/s read and 130MB/s write after installation?

Run a sequential read/write benchmark such as CrystalDiskMark or ATTO on a UHS-I reader; sustained results near 200MB/s read and 130MB/s write confirm expected performance.
