Thread: SD card size

Of course. If it is bigger or smaller, it can not fit :P

Sorry, but your question is wrongly expressed. You're actually thinking of capacity.
Generally has no effect. Even when the chip which is built very fast, that will not have any impact because the information transmitted to screen does not require huge amounts of data.
Most have an impact if the card is very poor quality. No name chinese, extremly slow, damaged...
And normaly, if it is some very old device, it can have a limit in terms of the maximum supported capacity, or type of card.
