Latte panda delta 432 SD card Read/Write speeds?

I was wondering what the maximum supported transfer speeds the latte panda delta 432 were. I can't seem to find this information online anywhere and white I know it has 32gbbof internal storage I was wanted to see if I could hold an OS on the SD card even at lower performance than just using a m.2 ssd. But in order to figure this out I need to know if it supports like uhs 3 or something like that.
