The one limitation you may run into is that the sandisk firmware will only recognize ~8000 files. That depends on the complexity of your file/folder layout. If your folders system has a number of levels or is very complex it will drop the number of files recognized.
That limitation goes away if you're using Rockbox. saratoga says that the limit then is the how many files can be created in a FAT32 file system that size.
What about these file system warnings on Amazon's product page?
- Reformat into file system other than exFAT may cause instability
- Only compatible with SDXC enabled device in exFAT format per SD Standard
