The 3DMark Storage Benchmark uses traces recorded from popular games and gaming-related activities to measure real-world gaming performance.

In 3DMark's Storage Test, the Black SN770 had an average bandwidth figure of 921MB/s for the three-game load tests and an overall average bandwidth for the complete test run of 657.51MB/s, the fastest we've seen to date.

As 3DMark's Storage Test includes game loading tests, we used it to see how much of an impact the Game Mode 2.0 feature made to the drive when it was switched on, and as you can see from the results above it makes hardly any difference at all.
