fire219 said absolutely correct. 500 MB/s == 4Gbit/s.
As of SD cards, it's impossible to get 104MB/s on current Rockchip SoCs. Apparently for stability reasons, they limited SDMMC controller clock to 150MHz, which means maximum theoretical limit in SDR104 of 75 MB/s. and this is really good, because it's x3 faster than in pre UHS-I. UHS-II is not supported at all. I haven't seen an SBC with it supported.
