So there is no additional gain from SATA 3 to 2?

I'm going to do some tests of my own this weekend--using remote play via PC.

There are enough limiting factors in a console to not make a bit more bandwidth count.

Of course. I only just watched the video and yes, like I said from the very beginning in the other thread, you see improvements because an SSD is an SSD but the interface in this case is a non-factor.

I said that too but people didn't believe in the one true prophet. Putting SATA3 in a current console is like putting GDDR5X in the Switch.

A switch is fast because of its ASIC - the management plane could sometimes use some more power but yeah, I get what you are saying.

Thanks for naming me a prophet, though! At least one guy appreciates my knowledge.

Because heat.

There aren't 2TB 7200RPM HDDs that fit in the PS4.

The only 1TB 7200RPM HDDs fitting are the "WD Black Mobile 1TB" and the "HGST TravelStar 7K1000 1TB"

The fastest 2TB HDD fitting into the PS4 is the "Seagate Firecuda Compute 2TB" ... only 5400 RPM but it is a Hybrid with 8GB SSD Cache... that should help loading times within games, f.e. reloading a level, multiplayer maps...

SSHD is the way to go.

5400rpm drives have higher data density, so they can be smaller for the same capacity. 7200rpm drives basically only have faster access times, so random read is better, as the required sector to jump to will pass again faster.
In a console, when loading game assets 5400 to 7200 shouldn't make much of a difference, if any.
