Questions about this item

How can I confirm the card is delivering the rated 100MB/s read and 90MB/s write speeds after inserting it?

Run a benchmark tool such as CrystalDiskMark or the built-in speed test on your handheld; sequential read should approach 100MB/s and write 90MB/s if the host supports UHS-I.

Does the package include a full-size SD adapter or must I purchase one separately?

The card is sold as a bare microSD; a microSD-to-SD adapter is not included and must be bought separately if your reader lacks a microSD slot.

Should I choose the 128GB, 256GB, 512GB or 1TB version for a Nintendo Switch library?

Pick based on how many large titles you keep installed; 512GB holds roughly twice as many games as 256GB, while 1TB doubles that again.
