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