Hiya. A few questions....
Did you test the 1TB blade with the PC, or only the Mac? Did you test the 2TB blade with the Mac, or only the PC? In each case, how is the blade connected to the computer?
Egad... why not APFS?!
We're talking about a 2018 Mac mini here, right? What size of internal SSD does it have? Take whatever benchmarks you ran against the 970 EVO on the Mac, and run them against the internal SSD instead. How do the results compare?
Cheers,
