Pretty much. Out of nowhere, SSD speed was the new war.
And by the looks of it, PS5's SSD which is more than double the speed of Series S/X (and possibly even more gimped as that thread said its PCE 3.0 or whatever), and it turns out S/X loads faster in all these game tests people are doing the past week more than half the time.
Give it a bit of time, and you'll see the whole PS5 has 5.5 gb/s (or 20+ decompressed)!!! feature disappear. It's week one and it's already shown it's no better than Xbox's 2.4gb/s SSD for games.
