Topic: Cartridge vs SD card vs Internal Flash Speed

Any idea of how fast the game cartridges are vs the internal memory and also vs (the fastest) MicroSD cards?

Curious if it's best to go retail or digital when I play.

Thanks!

SanDisk seems to have some interesting results.

I'm testing my Samsung Pro Select 128gb USH-I card right now.

With the Dragon Quest Heros 1-2 Japan eShop Demo, I have a 2 second difference between Internal vs. SDXC card (mine https://www.amazon.com/Samsung-Select-Memory-MB-MF128DA-AM/dp... Internal was 9 seconds, SDXC was 11.4ish to load to start screen before loading the playable demo portion.

Based off SanDisk, it seems the Switch would benefit from a USH-II card to match internal speed, but those are still quite expensive and not as large. Current USH-I cards most likely meet/ slightly exceed game card speed based of that SanDisk video. I have yet the opportunity to test this out.
