I got a 128gb Samsung EVO Select Micro SD card from Amazon to use with the NEO Z83-4U. When I put in the card, Ubuntu did not recognize the factory exFAT format of the card. I was prompted to format the card. The format choices were ext4, FAT32 or NTFS. I chose ext4, because it's the native filesystem format that Ubuntu uses. I read a bunch of blogs about Micro SD cards with different formats, and I wasn't sure if ext4 would even work. Yes ext4 works fine with Ubuntu, but exFAT did not. The only issue I had was file permissions. I had to use:
sudo chmod 777 /media/xxx
using the real device name of the card instead of 'xxx'. I found the device name by using the 'df' command when the card was mounted.
The only drawback of ext4 is compatibily with other operating systems. The ext4 formatted card was not recognized by my Kindle Fire HD 8 tablet for example. For compatibility with other devices, FAT32 is probably a better choice. I don't plan on using the Micro SD card as removable storage on multiple devices. ext4 works just fine for storing MP4 video files on the NEO Z83-4U, which was my main goal.
