In the spec they brag about 100Mb that is not "high speed"

SPI (20 Mbit/s)
The fastest SPI chips I've seen are 70 Mbits, but it's true that most of them aren't quite that speedy. On the other hand, most SDIO cards aren't that fast either (and don't use 4bit parallel signaling) ... in fact, every SDIO card supports SPI.
