I’m still figuring it out. I know ExFAT works across all desktop OS’s, NTFS works with Linux and Windows, and ext4 only works with Linux.
But it took a half hour of googling to figure out you can’t install Linux on NTFS. I planned to do that to ease cross platform compatibility. Oops. I’m also attempting a RAID 1 array using NTFS. It seems to work, but I’m not sure how to automatically mount it on boot. I feel like I might have picked the wrong filesystem.
