    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.)
