R89 - SD card reader speed?

[sparomba]

The officical Beelink website isn't very detailed about the SD card bus. It only says "1*Micro SD card slot".

Does it support: SDHC? SDXC? UHS-I? UHS-II?

I've read in one thread (1,2) that sdxc cards seem to work for some users. However I couldn't find any information about transfer speeds that the card reader of the R89/RK3288 actually can handle. Could anyone please test it or share his/her knowledge? Thanks in advance!

I tested it at Linux and it's something between spec 1.01 (12.5MB/s) and 2.00 (25MB/s)... if I remember correctly ~20MB/s...

Im using UHS-1 cards (e.g. Samsung EVO)...

EDIT:
~22MB/s
