I'm guessing something with big ass heatsink might not pass Sony certification. Sony and Microsoft are just using different m2 standards. Microsoft uses the smaller one like the surface. The PS5 uses the more universal standard.Oh sorry I'm with you, I thought you meant it had two by default. On that point, though; is there any kind of size uniformity for SSDs? Or are they usually small enough that it won't be a concern? Obviously the proprietary one MS has is pretty small so I'd assume they aren't very big but I'm not sure myself.
