It seems there may be a speed issue of some kind. A past thread mentions raw devices being fast but doesn't ntfs-3g use raw access.
ntfs-3g is the slowest then msdos gets around 2200 Kilobytes/s. The same msdos stick gets 12000 Kilobytes/s on Win 10. FFS is faster. Strange to me that usb hdd have always been fast with any filesystem. I will try a ntfs-3g usb hdd on a recent snapshot.
