I'll admit that I bought into the SSD hype though after Cerny's deep dive, but really neither console lived up to the marketing. Xbox hasn't really delivered on being the "most powerful console". And let's not forget Microsoft was extremely proud of their SSD tech too. Trademarked "velocity architecture". So yeah......all this "secret sauce" isn't really special at all.
The SSDs have kinda delivered with respect to load speeds and stuff like Quick Resume, though. The problem is, many people aren't interested in hyping up stuff as unsexy as that.
