Oddly, once full we were receiving better performance from the Extreme Pro based on an average of three runs, its performance matched what we saw from the 850 Pro in our single large file copy test.
This time when using the program data, the Extreme Pro becomes slightly slower once full, losing around 6% of the original performance once full.
This time just 3% of the empty drive performance has been lost in our game test once we filled up the Extreme Pro.
