It was explicitly stated by cerny in the hw deep talk he gave. Coherency engine which is part of i/o complex instructs gpu cache scrubbers on what to do. This happens behind the scenes, without cpu use and works for both internal ssd and the additional nvme ssd. Both ssd's connect to i/o complex.

Ideally, they would put it in an env test chamber at 35C, random read continuously at max bandwidth, and monitor the controller's temperature sensor (the one which would trigger a throttling). It would get closer to an obvious asymptote. Pass/Fail based on how far the asymptote is from the throttling threshold.
They already have samples from manufacturers to test, and they said the QVL would be published a bit past the PS5 launch. That might indicate an extensive testing and/or some back and forth with manufacturers to apply firmware fixes for performance or latency or priority issues. Software at this low level have a very long chain of validation. There's also enough time for manufacturers to comply with sony's thermal requirements.
We were talking about what they would do for consumers. I don't think every consumer has their own environmental test chamber.
Consumers would just buy the certified drives, is there anything more for them to know?
You store and can play your PS4 games on it. LOL. That would be a good consolation feature.
You will be presented by the message "A new system software is needed to downgrade the performance and stability of the system"
Well, benchmarks ... if not running a while, benchmarks won't tell you the full story.
nvme drives tend to not holding their speed very long. Overheating is issue no 1. No. 2 is, to small cache, ...
The Problem for sony is, they can't get past the internal IO of the nvme drive. To equalize that, it must be faster. But after all I've so far seen, I doubt that the ps5 drive can (or must) hold the speed at all time. Doesn't really make much sense that the drive should hold the speed for a longer period of time. Most times games should just quickly load something and than the drive has time to cool down a few ms and than the next load begins. It should not be the case, that a game loads data over minutes at full speed, at least I don't see a use case for something like this. Small bursts of data-streams would be more than enough.
For internal Sony will most likely have heatsinks that integrate with the systems air flow well. I would hope they designed some type of cooling. It could be dificult without thermal pads.

It's good to see you have a second Sony-related obsession to keep your Life of Black Tiger obsession company. One more and you get a free sandwich.
