| Bajablo said: my guess we are gonna stick to SATA 3 as we use now (don't know where your 500MB/s came from? since that is not a theoretical max on any of the SATA standards) but move over to disks (SSD) that actually can cap the interface. since you gain nothing form just expanding max bandwidth if the hardware (in this case, harddrive) can't push data fast enough to cap it. what we are doing now in consoles is sticking a 60-80MB/s mechanical harddrive on a 600MB/s bus.. it is slower than it could be even if we just stick to todays tech. Answer: SSD's on SATA interface. good price/performance compromise |
We all know that SATA 3 has a max theoretical bandwith of 600MB/s. I used 500MB/s cause in reality no one is going to be hitting that theoretical max on average. Even that 500MB/s isn't achieveable in real everyday use unless you are running some sort of test thing.
One thing for certain is that we can't stick to the what we are currently using now. Especially if next gen we have up to 20-32GB of Ram in consoles.
SSDs over sata 3 may seem reasonable, but thats still talking about a peak of about 550MB/s. And thats assuming that peak is hit often. But if they are goiing with SSDs, then they very well could use an M.2 interface. It gives room fro growth. The consoles won't have to ship with the NvME variant of those drives, but with the sata variant, which are significantly cheaper. Then the users could always upgrade their drives if they want better performance to the NvME variant.
