To be fair the PS5 didn't really dedicate anything at all to the cooling of the SSD. The chips merely contacted the plate with thermal paste.
yea but the plate and heatsink attached is extremely large with a lot of air flow.. I'm speaking more to the add on nvme drive. I have 2 and they get extremely hot and they are in a case with good air flow. The nvme drive on the ps5 is in its own sealed section of plastic and metal.
