Low performance on my SSD

[Francky Franck]

Hello,
I'm having low performance on my new Samsung 850 PRO 256GB SSD.
My two SSD are plugged in the white SATA 3 6GB/s port.
I'm having a brand new Sata 3 6GB/s cable for my Samsung 850 PRO.
Here's my low performance on my 850 PRO : http://i.imgur.com/AT6nBmN.png

Maybe if I install the OS on it ?.. I'm supposed to do it anyway but I don't think it will solve my issue.

Make sure you're not plugged into G-STA 6 or 7.
Try updating your IRST driver and see if that makes a difference (http://)
