This is because most NAND is still made on old processes and there has not been a compelling reason to really change this because size and power aren't issues impacting these components. There is a gradual swing for NAND on smaller more energy efficient processes, which will mean more NAND in the market from wafers so capacity (at the expensive of cost) will increase but the heat will subside.I remember commenting that it looked like there wasn't a way for air flow to make it into that slot. I also remember the debate about nand chips wanting to be really hot and additional cooling could damage them.
the way it looks , there wouldn't be much space between the plastic of the case and then the side panels. So even if you took off the ssd slot cover there might not be enough room to change anything.Could you not just keep the cover for the SSD slot off? Or is it needed for dust...
But their internal NVME Flash chips have solid contact with the heat shielding where as the expandable NVME does not appear to have any. You can see the contact points align with the flash chips, at least on the iFixit tear down.
It's same as any other ps5 rumor. First it of abysmal yields due to higher clock speed, then the fireball rumors and now this. Could be true, I'll wait and see what materializes in the end. It would be odd if sony didn't account for something like 10W max for ssd and plan accordingly. It cannot be surprise what kind of wattage ssd's output. Especially when sony designed custom ssd and should be very familiar with SSDs.
I guess it's a little different trying to guess ~2 years ahead of time what kind of thermal load other manufacturers solutions will have, and what kind of air flow is needed over the heatsinks they may or may not have, with heatsink fins perhaps orientated one way or another.
If there's any truth to this story, then I'm sure Sony will crack the problem. Even if it took a custom 3rd party device (which I don't think it will). PS5 is probably going to go to 100 million (or more) devices, so where there's the brains and the money there's almost always a solution.
I wouldn't be worried about this if I were a PS5 owner.
I just feel this is similar story as the yields due to clocks and ps5 will overheat rumors which both turned out to be not true. FUD is strong when sony is concerned. I assume sony would get info from samsung&co for needed cooling as ssd manufactures for sure want to sell ssd drives that fit ps5. If not take some older power hungry nvme ssd and assume doubling bandwidth doubles heat production and add a bit of safety margin to reach something like 8-10W cooling needed. If I can do this type of guestimate surely sony engineers can do better. Not a big deal to overdesign initial models and optimize cost down once dust settles.
Sony has spoken about game specific fan profiles. I wouldn't be surprised if sony tries to minimize noise by only increasing fan speed if external ssd is attached. I wouldn't be surprised if they even profile compatible ssd's and optimize fan speed based on how much heat each ssd produces. This could easily lead to misunderstanding and doom and gloom type of FUD when the intent of optimization is misunderstood.
I'm sure Sony will solve this - infact I have no doubt - but you're making the classic mistake of coming from a position of relative ignorance and assuming that Sony's desired solution is n00b level to implement.
