Of course, this was taken with skepticism, because such drives have long been used on PCs and no one is surprised. However, in the technical department Eurogamer (Digital foundry) stated that there is still a difference and it is much more than a simple download acceleration.
The bottom line is that the consoles plan to use GDDR6 memory, which will be both operational and video buffer. Rich Leadbetter from DF believes that this memory is still expensive, so it’s hardly worth counting on more than 12-16 GB.
According to Leadbetter, just such a bunch will allow you to almost instantly download games and switch between applications. However, it will be possible to find out exactly about this no earlier than the summer of 2023, and try it only in the fall.
