i want to ask about the transfer speed of the memory card. it`s written on the memory card as 45MB/s, 80MB/s... so does it affect when we take pictures? What i understand is that the higher number we use, the more rapid we can take picture. so it is good for the continuous shooting. Is it right?

I want to ask about the transfer speed of the memory card. It is written on the memory card as something like 45MB/s, 80MB/s. Does it affect anything when we take pictures?
