(PRettied up table, narrowed some columns, made dimention nomenclature more understandable, SecureMMC doesn't support 4-bit mode, as that's impossible with only 7 pins.)
(has anyone made mini-SDHC/XC cards? it's almost exclusively SD and mSD now that I know of. hence only editing those two...)

Table data compiled mostly from simplified versions of MMC and SDIO specifications and other data on SD card and MMC association web sites. Data for other card variations is interpolated.

Capacity limit in all SD/MMC formats appears to be 128 GB in LBA mode (28-bit sector address).[citation needed]
