This, This and so much this. I love when I see people try to hype up this like its the 2nd coming of SSD tech. I guess all Sony's other proprietary tech was so much better than their counterpart UMD, Sony memory sticks, etc. This is just a way Sony can charge you god only knows how much for an SSD drive so you can't just go buy a cheaper SSD drive for your PS5. Well at least until someone makes an adapter like with the Vita memory cards.
Whatever man, Sony can just shut up and take my money.
