Your company's own advertising materials promoting your proprietary NTFS driver (https://www.tuxera.com/products/tuxera-ntfs-embedded) claim that NTFS-3G is much slower than ext4: Read: NTFS-3G: 63.4 MB/s ext4: 113.8 MB/s "Microsoft NTFS by Tuxera": 116 MB/s Write: NTFS-3G: 16.3 MB/s ext4: 92.4 MB/s "Microsoft NTFS by Tuxera": 113.3 MB/s I'm not sure why anything you say should have any credibility when it contradicts what your company says elsewhere, and your company has a vested interest in not having proper NTFS support upstreamed to compete with their proprietary driver. (Note that Tuxera doesn't provide much support for NTFS-3G; most of their efforts are focused on their proprietary driver.) - Eric
