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.
The ADATA Legend 970 does a pretty decent job in the Final Fantasy XIV Endwalker Official Benchmark. It doesn't top any of the load results charts and even sits bottom of the Scene 3 and Scene 4 charts but still manages to be faster overall than the Seagate FireCuda 540.
