Mini 4s SD Card Read/Write speeds.

So I have the ifive mini 4s running fine since the latest firmware.

I have installed as internal memory:

SAMSUNG EVO plus 64gb UHS-1.
Rated:Up to 100MB/s read and up to 60MB/s write speeds

Actual read write speeds are read=20.97MB/s write=10.68MB/s

Card checks out on SDinsight app as genuine.

Are these speeds normal?

If not anyone know what might be going on here?

OK thanks, make sense. Should have bought a cheaper card.

Hello, this with the computer's USB interface, there are data lines are related. Data given by the SD card are generally ideal, it is difficult to reach this rate.

From what I understand, these tablets only support USB 2.0. So those speeds are acceptable within the written parameters. When I plug the tabdlet into my notebook, the tablet shows up 30mbs max. So, I would assume the tiff slot is using the same bus.

The speed of the bus doesn't bother me to much. I can still load an uhd video on my old SDHC. Does suck we have this fantastic screen and the slowest bus speed. :dizzy:
