Like you said the advertised read speed is 7000 and this is what it gets when reading reviews online, I suppose 6500 isn't too bad, but could be better.
It's one of the gen 4 drives that I will be using so thanks again for the benchmarks.
The speed are depends on how much storage you have left on the SSD. If you run the benchmark with just fresh Windows installation and drivers, nothing more you will probably get very close results to the advertised speeds.
