So I just installed a Samsung 970 evo on my Mac Pro 6,1, and according to disk tests, it's roughly 3 times as fast as the stock SSD (woot!!!!). I was expecting my new machine to be noticeably "snappier", but haven't really noticed it. Say when I "click on an app", I remember when I went to from my slow HDD drives to my first SSD and the "number of dock bounces" that apps had dramatically decreased, but I'm not "visually" seeing a difference either when doing that or using photoshop and was wondering why. Is there an app - similar to activity monitor that captures and visually displays data in an easier way (vs live) - say when you use photoshop? I'd like to see on one graph the CPU, Disk IO, and memory usage (and memory speed?) to determine what's the bottleneck?
