Thank you all for your replies.
I am going to read the 2 threads that got posted in the first answer.
Just a couple of quick response :
my source hard drive is on USB3 and I've check its speed with hd tune pro ... it goes up to 60~70mb/s (old HD). so 20~30 is below it's capacity.
I have no idea what UASP is ... but I'll look by myself before posting some stupid question.
indeed my transfert is between a windows computer (where the USB3 HD is connected) and my banana pro with OMV (where my SATA drive is connected, this one was checked to go up to 90~110mb/s) on some SMB share.
I'm hoping to get more transfer speed.
In the end I'm connecting a USB3 drive on a USB3 port on an idle computer, connected to a gigabit switch. Then it's the banana pro with OMV and just this one task : SMB share on a (fast) HD connected directly on the SATA.
... so if I'm not at the smallest of the 2 hard drive speeds, there is something I'm not understanding.
I might have some weird thing at the hard drive connected to the banana pro. I think (a while ago) I formatted it with NTFS. Then I could not create a file system. Then played a bit with fdisk and parted (by SSH), GPS and ETX4 and XFS, and all those stuff I don't quite get.
Then tried again a couple of times with OMV interface ...
Ok ... so maybe there is something twisted there. But I don't know how to check :/
