I have a RAID enclosure USB 3.1 Gen 2 with 2 SSDs inside.
The speeds I get on my ASUS Z170 Pro Gaming motherboard is strange. I connected the same RAID to both USB 3 and USB 3.1 Gen 2 ports.
The speed that I get with USB 3.1 Gen 2 is slower than USB 3 in case of 4k Q32T1 as you can see from the image above.
What gives? There is a problem with ASMedia drivers?
