Questions and Answers

Do you have you a question about the Samsung PRO Endurance 128GB microSDXC Memory Card with SD Adapter?

Q: I always use the excellent Samsung Pro Endurance SD cards for my dash cameras. What is the difference in this newly released Samsung Pro Endurance card? I see the new one is U3 class as opposed to the U1 class of the ones I currently use. Is this version better than the one I currently use in my Thinkware 1080p HD dashcam?
Answer by Website User on 10th May 2022
U3 is faster than U1 - if the U1 works, then you don't need the extra speed in your use case
