Review on 💾 SanDisk Extreme Pro 32GB SDHC UHS-II Black Flash Memory Card by Andy Mitts

I received the card yesterday and immediately subjected it to the CrystalDiskMark test. The results were very disappointing. I got about 19.5 MB/s read (19.5, 19.51, 7,14,5,99) and 18 MB/s write (18.46, 20.01, 2.15, 1.97) receive. The speed standard of this card is the speed of the most ordinary SD card! nothing "extreme" at all. One reason that comes to mind is that the card is UHS-II and not UHS-I. UHS-II has 2 rows of pins while UHS-I has only 1 row of pins. When UHS-II is inserted into a UHS-I reader, the card essentially becomes UHS-I. I'm not sure if this is the reason. I am returning the card to Amazon.
