SanDisk Ultra microSD UHS-I cards are ideal companions for high-performance Android smartphones and tablets. Fast transfer speeds of up to 100MB/s and Class 10 video rating for high-quality HD video recording
better smartphone experience.
Waterproof, shockproof, x-ray proof and temperature proof to protect your memories
Warning: these have poor write speeds and are no good for 4K video / GoPro / drone footage. The transfer speeds they refer to are sequential read speeds. If you want something decent, get a Sandisk Extreme or Extreme Pro.
Certainly 4K requires U3 A2 cards.
Poor write speed == 3D QLC. Endurance takes hit too
is this good enough for Switch games?
Yes, definitely sufficient for Switch
Matches the Switch's read/write capabilities so yes.
Good enough for cheapo security cameras?
Yes, most of the security cameras are 1080P. Class 10 cards are suitable for up to HD recording.
Should buy an endurance card for this as well by that logic?

May not last long with all the re-writes, though, you might want an "endurance" SSD.
Would this be OK for a Samsung tablet?
Can i used this sd card for Samsung note 20 ultra?? Or any other phones??
Not advisable if you're going to be shooting videos. Spend the extra on a SanDisk Extreme card. It's not that much.
Why not order from Umart For $21+ a $9 item, and get it for $10?

Decent price but be aware this is class 10 only, not U1. SanDisk has another red colour 128G Ultra card in class 10, U1, and A1.
