The PlayStation 5 warranted little more than a mention when it was introduced at CES back in January. Sony was planning a much bigger reveal in a few weeks at GDC in SF, but, well, COVID-19 happened. So here we are with a live-streamed version of the event, offering far and away the deepest dive into the next-gen console.

Lead system architect Mark Cerny kicked off a low key presentation to a small gathering of people — a direct response to on-going social distancing concerns. The event did, indeed go deep, at Cerny discussed how Sony enabled the 5GB/s SSD — the most requested new feature from developers. The system is said to potentially be nearly 100x faster than the PS4’s I/O.
