The Final Fantasy XIV Endwalker Official Benchmark uses actual maps and playable characters to assign a score to your PC and rate its performance including scene loading times.
The benchmark gives an overall load time as well as loading times by scene.
Corsair's MP600 Elite with Heatsink does a decent job of the Fantasy XIV Endwalker Official Benchmark. In four of the five scene load times it sits in the top 5 timings and in the one that it doesn't (Scene 4) it's still in the top 10 and so overall it's the fourth fastest Gen 4 2TB drive we've seen to date in this benchmark.
