Whats here not to understnd?
- SaTA 2: Theoretical peak performance 375MB/s. Realworld performance is determined by a number of factors. Drive technology being used and what other things the HDD is doing. Bottom line is that you end up with a average transfer speed of around 70-150MB/s based on if you are using a 5400/7200/10000rpm disc drive and around 250-290MB/s if you are using an SSD.
- SaTA 3: Theoretical peak performance of 750MB/s. Real world average is at around 500-575MB/s. Only way to hit that over a SATA 3 interface is with an SSD not a HDD.
Why is this complicated? Unless you are intentionally making it complicated?
Now there are tons of other factors that affect how any drive performs. But this factors are always fixed. This part is more complicated and what I've been avoiding getting into cause I was trying to keep this topic as simple as possible.
Simply put, you will get the best performance you can get from a drive interface combo on a PS4pro when using an Sata 3 based SSD in the PS4pro than you would any other solution available.
Now let's not even look at transfer speeds as we don't really know what system overheads contribute to the PS4/PS4pro performance. Because if a certian amount of transfer bandwith is tued up by the OS thst amount will be constant regardless of ehat drive you out in there. So let's just look at the tech employed instead.
If A HDD (5400/7200/SSHD) over a Sata 2 interface gives you (60/52/48secs) loading times respectively then using a Sata 3 drive (7200rpmHDD/SSD) will give you around (42/20-30secs) respectively.
