hi
i have seen some circuits and all have the same "not ideal thinking" about SD Card.
the most creator think this for SD CARD
SD_CLK ( IO6 )
SD_DAT0 ( IO7 )
SD_DAT1 ( IO8 )
SD_DAT2 ( IO9)
SD_DAT3 ( IO10 )
SD_CMD ( IO11 )
be sure your circuit is well mean - this are pins for the SPI Flash
and just in time there is no sharing code available with this as SD Card and SPI Flash
the SD Card Demo example is on this pins
SD_HOST_CLK ( IO14 )
SD_HOST_D0 ( IO2 ) ( switched for Firmware flash )
SD_HOST_D1 ( IO4 )
SD_HOST_D2 ( IO12 )
SD_HOST_D3 ( IO13 )
SD_HOST_CMD ( IO15 )
hope this helps
best wishes
rudi

do you plan SD CARD SPI Version ?

Yes, the SD SPI driver is almost ready! Hope to release it soon.do you plan SD CARD SPI Version ?

for completion now:
SD Mode
like the Demo in ESP-IDF
you can use 4Bit Mode (Dat0, Dat1, Dat2, Dat3) or 1Bit Mode (Dat0 )
SPI Mode ( driver comes like Ivan sayed )
you can drive by usually SPI Master then with MISO, MOSI, CLK, CS
