It would work fine for the use case which is loading large 10+ GB texture sets into memory on a continuous basis. And random isn't terrible, its still quite good for reads.
And write endurance hardly matters when you are talking about a use case that is realistically single digit drive writes per year. If someone is buying and downloading enough games to run out the write endurance, I think Sony would be more than happy to fix the drive for them, that's basically ~1k games AAA games per year on a 1TB drive over 3-5 years. Hell, if your consuming games at that rate, Sony will probably just give you another full console.

An 8TB SKU isn't going to be $400 just like currently there are multiple SKUs based on capacity. Right now they spend between about $60 on storage related costs for the current consoles. So realistically you are probably looking at a ~2TB entry point.

There's no redoes. Its a custom SOC, they will put in what is required. And as I said, if they support HDD, it will be via USB3 which is available on both PS4 and XBONE currently. There is zero reason to have SATA on the console.
