Does SD class have an impact on smartphone performance?

I realise a higher class obviously means higher read/write speeds, but would it make a *noticeable* difference on a smartphone? Could you tell if it was class 4 vs class 10?

Not really, Class 10 cards are just faster to load stuff onto from your PC, that's why I have one.

If you have some heavy duty games installed on sd card maybe or 1080p video recording maybe, but have even read that class 4 are better for some things on phones due to it handling smaller files better (wasn't sure what to make of that tbh)

That's not Class 4 in general, just higher quality Class 4 cards. A no-name Class 10 card will have far worse random read/write speeds than a branded Class 4 card. When they're both the same brand/quality, the Class 10 will always be faster.

Was a link I was pointed at

Too many numbers...I'll take your word for it, maybe my understanding of SD cards wasn't what I thought it was :p.

I never said I understood it, but the random r/w figures seemed better on lower class cards.
That said they look a little screwy as some write faster than they can read....
