Saying the 970 can do 3500mb/s is great but actual read speeds will be considerably lower after populating the drive, I have a 960 pro 512gb, ok so when i got the drive it did read at 3400mb/s but after migrating my Windows 10 it soon fell off, I currently have 81gb free from the available 428gb and i get just under 2400mb/s seq read/1800mb/s seq write, so i think poputaled drive speeds should be used instead for comparison.
