NTFS Performance Enhancement on DiskStation

Fascinating! I am actually considering the value of having one of these just to use as an upload station for portable HDDs .. especially NTFS ones that seq providers give 

If you take a new external hard disk, plug it into DiskStation and have the external hard disk formatted to EXT4 file system, the writing speed can be more than doubled. But most Windows users prefer to use a NTFS external hard disk so it can be recognized by DiskStation and Windows operating system. Therefore, in DSM 4.0, significant improvement was made to NTFS writing performance.
