so Sony has a storage technology which is more than 2x faster of the current or near future state of the art and costs, what? 50$ per TB... well, some receipt is definitely needed
The cost part is interesting, because it requires less but faster RAM than a normal drive. It very well could be cheaper than a regular SSD in production, the downside is the years of engineering and it not being terribly useful outside of game consoles. If Sony sends all the controller stuff to a Ryzen CPU core instead of an embedded ARM chip, the speed/cost potential is even higher, with a little extra anxiety about stability. The usual dedicated OS core is probably overkill with a CPU that fast, probably no problem giving it an extra task. Iirc, the reason there's a dedicated core is for I/O encryption/decryption, so it might make a lot of sense to do it that way. I just don't remember if that was a possibility in the patent.
To echo gofreak's reminder, just because there's a patent doesn't mean they're using it. They could've run into issues making the low-level file system code stable for all we know.
edit:
I'm watching that interview of Todd Howard now, it's quite good. Anyway, so as he says MS and Sony won't be screwing up at the starting line for next gen. But I'm sorry, if Sony ends up having a big advantage with their loading and streaming solution i definitely would call that MS screwing that part up. It's for sure gonna make a good amount of gamers change their console of choice, I sure will, especially when BGS games like TES and mainline Fallout games are very big reasons why I game.
I wouldn't call it a screw up on MS's part if they've got a decent m.2 SSD in their system. They'd have longer loads and less streaming capability*, but it'll be in line with PC specs, so it'll be perfectly fine for everything running on the system. The only games it'd hold up is third-party console exclusives. The PS5 would be better in that regard for third-party games, but the Xbox might have other advantages.
*again, assuming the full potential of Sony's patent is reached.
