Which SD card formats work in the SD card slot?
Cards that conform to the SD 1.x and 2.x standards should work. The SD card slot can use cards that are Standard SD (Secure Digital) 4 MB to 4 GB and SDHC (Secure Digital High Capacity) 4 GB to 32 GB. MMC can also be used in this slot. MiniSD, MicroSD, and higher density formats like MiniSDHC and MicroSDHC can also work with the use of “passive” adapters that conform to the width and thickness specifications listed above. Example of a passive adapter: What is the maximum speed that my computer can use when reading and writing to an SD card in the SD card slot? Your Macintosh has a maximum speed of 240 Mbit/s for SD media using the SD card slot. This exceeds the transfer rate of most SD media. Check the packaging that came with your SD media to determine the maximum transfer rate used by that media. Does the SD slot work with cards that exceed 32 GB? Yes. However, most media manufactures preformat the media using common block-and-cluster sizes that do not approach the theoretical limits
