I have a ocz vortex and a Samsung 850 Evo, listed below in order. Why are my Timing buffered disk reads so much better than his ‘Timing buffered disk reads: 576 MB in 3.00 seconds = 191.84 MB/sec’ ? With the Sandisk Extreme Pro, shouldn’t the Timing buffered disk reads be better?
I am using just normal Sata cables on a 5 year old motherboard.
