I have just started using a USB 3 external drive for my backups and I find that it is actually slower than my previous USB 2 drive.
I have played around with SF settings like using Windows API etc., but no joy.
I understand that this is not a SF issue and perhaps I need to update my driver/hardware in my PCs to be USB 3 compatible.
However, it will be very useful for this and other troubleshooting if we had a dynamic display of the transfer speeds (Mb/sec) during the job to be able to understand whats going on.
