the review shows very fast read and write speed as compared to Sandisk Extreme pro.

I don't know about its performance with the adapter on.

Do you guys know why?

The market for phone memory cards is huge and very competitive. On the SD front, not so much. So they sell SD cards for a bigger profit, especially since they ship a lot less of them. So that's the economy of scale.

Lucky for us, memory cards in general are already very cheap and fast enough, i have to recharge the battery on my camera multiple times before i even fill up my 16gb card with jpegs. A typical 32-64gb card can hold thousands of images, for most people that's enough to store all the photos they take in a entire year!

We don’t all shoot JPEG , hence for the majority on here who are likely to shoot RAW those 32 or 64 Gb cards are likely to hold a few hundred images .

I have certainly gone out and filled two cards in one shoot , and I have several dozen so that I can cover big jobs without fear of running out .

I can’t say that I’ve particularly noticed price differences between the two types - my local Tesco tends to have them side by side at very similar prices - confounded slightly by the various offers which come and go week by week - sometimes even having a few of a certain card type reduced to a fraction of the normal price , with identical cards on the next peg at full price!

No difference in speed with or without the adapter. Nil.
