Micro sd for 4k 60fps

You’d only need the faster card for anything with increased data rate. For any given resolution it would require a reduction in compression to achieve this. Going from H.265 to H.264, for example.

Go for the Samsung or SanDisk with the highest write speed supported by your phone. Write speed is what matters for high Res photos and videos.

The above point about external storage is valid as it is important to have back ups

Hello, at the end I bought the galaxy s10 plus, I have a very fast micro sd on it but the phone by default saves 4k 60fps videos on internal memory only, so in the case you record at 4k 60fps you have to save them to internal memory, later you can copy them to sd card if you want

Tell me about it. SD card ratings are absolutely ridiculous.

I was looking for a card too and found a sandisk extreme card. It has the following markings on it:

I, U3, A2, V30

So lets go to the sd card website to check what it all means.

Application Performance Class - SD Association
Speed Class - SD Association
Bus Speed (Default Speed/High Speed/UHS/SD Express) - SD Association

I = 50MB/s (SDR50, DDR50) 104MB/s (SDR104)
U3 = 30MB/s minimum sequential write speed
A2 = 10MB/s minimum sustained sequential write speed
V30 = 30MB/s minimum sequential write speed


Seriously, all these figures on the SAME memory card? Seriously? I'm an experienced IT consultant of over 20 years and this is all absolute gibberish marketing buzzwords. I cant believe you need to visit three separate web pages just to decipher what plain speed/plain specification all these nonsense trademark buzz-logos equate to.

Why not just write the speed specifications in PLAIN English on the product description or on the back of the packaging? Why do they need to put these nonsense buzzlogos and then make you view several pages on the SD card website just to decipher it all?

When will it stop? 5 years ago it was just simple (yet still silly) Class 2, class 6 etc. Now they have Class, UHS class, App class, V class, U class. In another 5 years they will have T class, Q class, BS class, Z class, Y class, UUUHS class, SDRDDR2000, and it will be 500 times more confusing to buy an sd card.

Memory card associations have gone absolutely bonkers.

You are right, absolutely, it's pure marketing. What do you need to know anyway?
