Microsd write speed

Does anyone know what write speed I’d need for the ultra smart hub for 4k recording?

Arlo recommends Class 10, the smarthub supports up to Class 10 UHS-3 V90.

I use Samsung EVO Select cards in mine.

thank you! I guess a better question would be what is the required write speed for 4-ultra2 cameras in 4k and 1 essentials camera in 1080p? V90 cards are expensive. Also do you suggest that I use a high endurance card designed for security cameras or would a regular card work?

Arlo says they support up to V90, not that you need one.  The one I posted above works fine (and the current version is v30). It costs less than $20USD on Amazon.  I use 128 GB, which is enough for several months in most situations.

Not sure how much high endurance matters (prices seem to be the same as cards that don't advertise that).  The base is only recording when motion is detected, so the card isn't exercised all the much.
