According to Johan Conradie (Destroy All Humans!), PS5 and Xbox Series X SSDs will mark a revolution

Indeed, Johan Conradie, Technical Director of Destroy All Humans! - Remake, decides to speak at GamingBolt's microphone to once again highlight the performance of the SSDs of next-gen consoles. According to the latter, the two SSDs would simply bring a revolution in the world of video games by reducing (or eliminating) loading times.
Having this level of IO performance is a fantastic improvement over our current hardware. You'll see a revolution in next-gen games where load times are either minimal or eliminated altogether. Johan Conradie, Technical Director of Destroy All Humans! - Remake
The technical director also adds that despite a less powerful SSD for the Microsoft console, that the latter will still mark a clear demarcation with the current consoles. He also specifies that the Xbox Series X will have a slightly higher performance bandwidth, however, according to Johan Conradie, the PlayStation 5 will remain for developers the "platform of reference".
PlayStation 5 will be the benchmark platform for processor optimization and the goal would be to achieve the same end results on both platforms. Johan Conradie
As a reminder, the Xbox Series X is expected for the month of November. The console will be delivered with many productions such as The Medium, Scorn or Tetris Effect: Connected. The PlayStation 5, meanwhile, is still expected for the holiday season.
