How does the Class system of SD cards work?
I know it's to do with the write speed of the card but if a Class 4 card is specified would a Class 10 card work OK? (a bigger number's better, right?)
Edit, wrong forum, sory
Yes more is better, I can see no application where a class 10 card would be incompatible with a class 4 application.
In short there are 6 classes
Class 2, 4, 6, 10 the higher the class the faster the transfer rate the number reflecting the speed in MB/s so a 2 is 2MB/s and a 10 is 10MB/s - class 2 can't store HD video either.
There are also 2 classes above this UHS1 which also has a transfer rate of 10MB/s - what makes this different to Class 10 I don't know and UHS3 which has 30MB/s for 4k recording.
Excellent, thanks, need to get a card for a GoiPro Hero, the manual specifies Class 4 for video but they appear fairly uncommon but you can get Class 10 cards pretty much everywhere
Gopro needs a class 10 to work correctly else you dont get the frame transfer rate
Be careful where you buy them, a lot of the cheap unbranded ones are crap.
I use 7dayshop their own brand stuff is pretty good VFM.
