For some reason i cant post any of the photos i took of the write speed tests but on almost every single set of tests each test consisted of four independent passes i had one pass that was in the 140 mbs range whereas every other pass would be in the 220260 mbs range

So yes the card is plenty fast but is inconsistent

There was another review with an image posted where results were under 30mbs in the image

I suspect the person inserted the micro sd card directly into the micro sd card slot in their computer which is only a standard uhs speed and cant perform either a read or write operation at above 30 mbs regardless of how fast the card is

You would need a highspeed card reader plugged into a usbc port to get the maximum results from the card

I know this because i tried measuring the card speed both directly from my computers micro sd slot which resulted in read and write speeds under 30 mbs and with a highspeed reader plugged into the usbc port of my computer which resulted in the much faster readings i mentioned above

And lastly the speed of the card did not vary at all whether i measured it with the adapter or without as measured through my highspeed card reader
