Hi guys,
I recently bought a second external hard drive.
Copying some movies in to it I noticed that the speed was at max 30-33 MB/s even though I had it on usb 3.
After experimenting I realized that when only one of my external HDDs is plugged in, the speeds are as they should. But as soon as i plug in a second ext. HDD they fall down to 30MB/s.
I tried all my usb3 ports and nothing worked.
I even tried changing the policy to "performance" from the device manager.
Is it normal? Is it a limit of the southbridge or something?
