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 [[gigabyte|GB]] in [[logical block addressing|LBA]] mode (28-bit sector address).{{citation needed|reason=SDXC could be much larger than 128 GiB|date=September 2010}}<noinclude>
