Do not store 96gb of anything on exfat, use ext4 or APFS or zfs or some journaled file system. Does NTFS really have a 4GB file size limit? Structures should match exfat so that part seems suspect to me.
No, but FAT32 does. Exfat, on the other hand has a file size limit of 16 exibibytes. That, combined with exfat's cross-platform mounting (NTFS has a lot of limitations in this regard) makes it a superior formatting system for flash based offline file transfer.
On a network? Use zfs+ or something.
