Re: Which SSD Drives Will Be Compatible With PS5?

@Cybrshrk it reduces cost. I'm not implying that the system sells with 2 NVMe units; if the expansion doesn't have to perform at the same level as the main unit, then it's cheaper to upgrade.

If a 1TB 970EVO NVMe can be had sub-$150 (maybe by then), which isn't on par with the OE PS5 unit, then you'll save a lot of money vs. an expansion unit that'll match PS5 SSD spec.

I see this working with slower (in comparison) NVMe solutions. The master drive will allocate a set amount of space for files to cache from the slave drive. SSD file seeking is only slowed by smaller file sizes, which seems to be what Sony is eliminating with its new file structure. This is likely why hybrid SSD work better with PS3/4 in contrast to speed gain from full SSD units.

So your main drive will preload larger files into place seamlessly with small executables configured to launch games from the main drive. As data is needed, it's transferred to the main drive to act as a high speed cache, thus negating the need for equally matched speeds up to a point.
