UHS-I Bus speed compatibility

Hello,

I was wondering what is the compatibility with the UHS-I bus speed norm.

Does the card reader have full potential for reading/writing UHS-I certified SDHC/SDXC card (bus speed of 104MB/s (SDR104)) ?

It probably depends on the exact MacBook model, in my case it's a MBPR.

Thanks for any insight !
