I upgraded my ssds to 970 pro s . I have one for the operating system and one for the games . Both ssds are running at 3.0 x 4 . When i copy from the one 970 pro to another the ssds are working only at 40 / 100 active time and they are copying at 1,2 gigs per second . Can this be a limitation from the operating system ?can anyone has any insight ?
