Hello.
Today some measures:

On the USB3 Key, i put a very big file of 61 801 717 760 octets. It is
100% of the only ntfs partition.

Copying on a internal disk file this KEY  mounted on USB2 is 36'38" with
windows and 36'21" with ubuntu. The rate is  28 MB/s.


Copying on a internal disk file this KEY  mounted on USB3 with an extended usb2 cable of 10 inches is 31'40" with windows and 29'36" with ubuntu. The rate is  35 MB/s with ubuntu and 33 MB/s with windows.
But another test with ubuntu and working a little on internet give a laps of copy 34"37". Rate is 30 Mb/s. So i say that it is the same result between windows and ubuntu.

Copying on a internal disk file this KEY  mounted directly on USB3  is 21'27" with windows. The rate is 48 Mb/s.
Copying on a 'nul' file this KEY  mounted directly on USB3 with windows is also a rate of 48 Mb/s.
( copy   fic1   /B > nul)
