ExFAT is FAST. FAT32 is SLOW. ExFAT does NOT have file size limit of < 4GB/file. As some people here use their tablets and load them up with BluRay rips, this becomes an issue with FAT32 filesize limitation.
It's not really an issue with specific SD cards.
I've used the exact same SD cards in ExFAT format and the TF700 never locks up (ICS). Ever since JB, it's been having issues.
But the recommended SD for Micro slot is SanDisk 32GB Class10 (it's grey/red)
I got a Transcend 64GB Class 10 in the Dock, no prob.
i think i have an idea of what is causing the issue. I did a test last night. I have a 32gb fat32 and a 64gb exfat. Both cards have the same data on them. On the 32gb, which is new, i loaded all of my stuff, except movies and music. The device ran great. So i got home, put in the 64gb, no movies and music, works fine. I then transferred several movie files (mkv and mp4) and music to both cards. I put the 32gb back in, went to play a movie in BS player, and it wouldnt play. Music would not play either, using stock player of poweramp. 5 minutes later, it rebooted and got stuck on the logo. I did a reboot, put in my next card. Same thing happened. I removed the movie files from my 32gb, and it went back to working great. I did the same for the 64, and had the same success. I left one mkv on the 32gb and have no issues. I added more than one movie file to the 64 and the issue is there. So i'm guessing that the issue involved the type of files and the amount of files on the memory card. I assume its music and movies, because i have tons of comics on these cards and have no issues reading them. So maybe if people can run similar tests, we can try to figure out why the tablet keeps rebooting.
