That's really expensive in comparison to the console prices, especially XBSS and it's 500GB SSD. I can see why SNY didn't go that route.
The good news is that PS5 consoles should work the same way.
This is why I like sony solution better, just allowing normal SSDs, and useing normal ports.
Which "normal SSDs" can be added to the PS5 where games can run from?
We still need a compatibility list!
Pushsquare's guess is that only the 980 Pro will meet the needed specs:
I think pushsquare are looking at the 7.5GB/s figure for PS5 SSD... which is why they think 980 Pro is needed, forgetting that the 7.5GB/s is compressed speed. PS5's ssd actual speed is 4.5GB/s (presumably read, or maybe both read/write) which several SSD's on the market can match.
We definitley need that compatibility list, however I imagine this is more of a "this will definitley work" list, and that SSD's not on the list will also work assuming they can provide good enough performance.
I don't see why SNY wouldn't, if they could, allow for any NVMe to work in that slot. Now while the system may tell you that specific NVMe drive won't play games directly because it's not up to snuff, someone like me would like to use it as back up storage that can be transferred to the on board SSD.
The transfer speed from a slow internal NVMe to on board NVMe should be remarkably faster than external USB 3.0 (HDD) to on board NVMe. It would also allow for a much cleaner look not having a separate external drive.
Is it likely the PS5 will have to use a certain speed NVMe, period? I know that's what I got out of the Cerny presentation, but other than requiring that speed for direct play, is there an obvious particular reason why just any drive couldn't be used for back up purposes in that slot?
