Does Linux use NTFS?
If you mean a boot partition, neither; Linux cannot boot off NTFS or exFAT. Additionally exFAT is not recommended for most uses because Ubuntu/Linux cannot currently write to exFAT. You don’t need a special partition to “share” files; Linux can read and write NTFS (Windows) just fine.
Is ext4 faster than NTFS?
3 Answers. Various benchmarks have concluded that the actual ext4 file system can perform a variety of read-write operations faster than an NTFS partition. As for why ext4 actually performs better then NTFS can be attributed to a wide variety of reasons. For example, ext4 supports delayed allocation directly.
