@Adaiah Not that I'm buying into the whole SSD hype put forward by Sony, but you have quite a few wrong points there. First, hardware-wise, there is nothing spectacular about the Series X SSD: there is no shortage of today's PCIe 3 NVMe drives that far outperform those Series X numbers -- in fact, those numbers look very near to a cheap QLC NVMe drive. In turn, the PS5 has something new and unseen in the PC world: performance in-line with the still unannounced future PCIe 4 Samsung 980 Evo drives. Will this difference in SSD speed be that importat for gaming? Probably not. But facts are still facts.
Furthermore, the PS5 does have internal storage expandability through an additional user-accessible m.2 slot. That is, once those standard Samsung 980 Evo drives are announced, you can expand the PS5 internal storage with those standard Samsung drives (and probably other SSDs from other brands that meet the same performance targets, as competition is a thing and that slot is very much standard -- unlike Microsoft's proprietary slot).
One thing we do agree on, pricing will be a deciding factor. But your arguments about storage are simply wrong.
