Nintendo recommends SD cards up to 32 GB however the internal SDIO controller seems to support SD cards up to 2.19 Terabyte (32-bit sector number). It's unknown if it really can handle that much. 128 GB was tested and works fine however it causes a major slowdown of the system especially at boot.
Nintendo recommends SD cards up to 32 GB. The internal SDIO controller seems to support SD cards up to 2.199 Terabyte (32-bit sector number). Up to 2TB (AGI TF138) has been tested and works, however larger SD sizes increase system boot time. The larger the SD capacity, the greater the bootup slowdown. 64-128GB tends to be the sweet spot for most users, with only an extra 0.5-1.0 seconds added to boot time as the tradeoff for the larger size.
SD cards should be formatted FAT32 with a 64KB unit size for maximum compatibility.

* Tests were made on NEW2DS 11.16.0.49J and OLD3DS 11.15.0.47J.
* Boot time is the time until you see the home menu (software icons are still loading) after pressing power button.
