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 Crucial T700 does very well in the Final Fantasy XIV Endwalker Official Benchmark topping three of the five scene load trace results. Overall though, it sits in second place behind Gigabyte's AORUS Gen5 10000 drive.
