I bought this 128gb card together with ProGrade Digital CFXB,SDXC,SDHC USB 3.1 GEN 2 READER. Check the speed using the h2testw V 1.4 software and disappointed: Write speed-323 MByte/s, Reed speed - 294 MByte/s. What is wrong?
The read and write speeds on the card are theoretical speeds that are valid only in a perfect scenario. Nobody really gets the card to work at those speeds. Now the question why one card can be slower than another, it could be the drivers in your computer are slowing down the card, it could be you are connecting the card reader to a USB hub that is slowing down the card, it could be the USB cable you are using is slow, it could be the card is defective. There are so many variables unfortunately. If ProGrade is working faster for you I would recommend returning the Sandisk and getting ProGrade cards.
