I meant internal SSD. The whole discussion had been about using an SSD thst has peak theoretical bandwith of 550MB/s over a SATA 3 interface. Of course we knkw there is a mechanical disk limitation. I referenced that in one of my earlier posts. 

Not all SSD's have peak rates of over 200MB/s. It's not just a mechanical disk limitation.

Ok, i don't know what this is about....

But let me be clear on what my point is;

With PS4pro using a SATA 3 interface, it means it has support for Drives that can take advantage of a 6Gb/s bandwidth. 

So as I have said, with the right hardware combination on the end users part (using a SATA 3 based SSD that has bandwidths up to 500MB/s+) you will no doubt get significant gains in specific use case scenarios (also like I have already pointed out earlier in this thread) when compared to the previous data 2 based interface setup. 

Unless you are trying to tell me that if I put in a 1TB Samsung evo drive into my PS4pro I will not get any meaningful benefit when it comes to load times (and I also pointed out exactly what kinda load times I was referring to) when compared to using a sata 2 based drive or even the same Samsung SSD over sata 2. 

The only other limitation will be on the cpu side or in a more crazy situation the devs coding their game in a way that such benefits can't be had. Now as for the CPU side, tons of random reads may be an issue, but that's not the kinda use case we are referring to here, I am talking about situations where a game has you staring at a loading screen for 30-60secs cause it's moving data from the hard drive. Now if that happens over a sata 2 interface with a 5400rpm drive with peak theoretical bandwidth of 150Mb/s (I keep using theoretical cause we both know that you don't always get the performance advertised on the box) going onto sata 3 with an SSD that has peak theoretical bandwidth of 550Mb/s ; will no doubt be doing better than the previous case scenario even when considering the same performance overheads. Unless the hardware (South bridge or cpu) just doesn't support such higher transfer rates. and there is no way we can know that till someone puts in a sata 3 SSD in the PS4pro.

I don't think Sony would have put in a sata 3 interface in the pro (while the PS4s still has sata 2) if there won't be any benefits.
