That would be true of pretty much all microcontrollers. Nutshell version, most MCU use SPI mode to talk to SD cards - printrboard (and sanguino) included. SPI mode is an older access method for SD, and most modern devices use the SD Card association defined "SDIO" (technically the tech standard name not the protocol, also used to talk to wireless modules sometimes... but I digress). Most ARM chips support SDIO, and this is how they communicate to their bootcards etc on Pi's and A10 tablets etc...
Now - some vendors of cards, with the switch-up a few years ago to SDHC, dropped SPI support on SD cards that are =>SDHC standard spec. The most notable being Kingston. This means that >2GB Kingston SD cards may/may not work when used with most microcontroller SD card setups.
But on the bright side - Given the SPI bus speed of an MCU; theres no point burning a high-speed class-10 card or the likes in the device anyway - Making these perfect candidates for reusing the older spec SD cards you have anyway or buying those dirt cheap ones down at the local camera store... Just stick to 2GB or less, or make sure to use SanDisk or some other brand than Kingston when using >2GB...
