Well that is true, the number will rise until release of the console, but I don't know what games you are expecting to play so I wouldn't plan on counting PS5 fully compatible for you.

100 is not great if they are focusing on the most played ones. That would be like many CODs, Battlefields, Fifas, Maddens etc. Games that have an online component to them. I don't know. Its not the end of the world. Would just be a nice bonus if it was fully BC.

That isn't it. They have looked at the top100 played games (and they didn't say the timeframe).

And also that doesn't mean only these games work, just that those are what they already tested, because of time constraints. Also as someone said it is very possible that the 100 is what they done boosting testing (like Pro where all games worked but not all had increased performance).

Would they though? I know it happened on optical disks, but pretty sure it didn't happen on the mechanical ones.

Sony's original claim was for 5.5GB/s of real-world throughput.
7GB/s would need to be verified by actual real-world benchmarks... Or Sony is leveraging compression to achieve such a throughput, which the PC can technically do as well.

Or they are just bullshitting to big-note themselves, not the first time console manufacturers have done that. - How did those extra ACE units go? Or the Cell? Or the Playstation Optical Laser? Can go on...

Yes. Sony's claim(and only) throughput is 5.5GB/s of raw data. MS's own is 2.4GB/s. That 7GB/s number is sony's compressed "equivalent" throughput. So basically 5.5GB/s of real-world data would still be sent but after decompression its equivalent to 7GB/s. And no one is saying that can't be done in PCs a well.

The reason sony needs PC SSDs that has a bandwidth higher than 5.5GB/s (truth is sony didn't even say they needed a drive higher than 5.5GB/s and this is coming from DF), has something to do with 6 priority something on PS5 vs 2 on PC SSDs and PS5 APU has to arbitrate the other 4 or something like that.

I'm not nor have I ever been about what can be done on PC and can't, but to be fair, at the time when Cerny actually said what he said back last year (and he even alluded to this exact observation himself during talk yesterday) there wasn't a PC SSD out there that was as fast as the PS5 SSD.

And to be fair I would think you should know better than bring up RAID... that's like comparing apples to oranges. Cause I doubt when anyone talks about having a single off the shelf SSD solution to put in their console or PC they are talking about a RAID setup.

Not really, compressed PS5 can get 9Gb/s worth of data (peak of 20 depending on the case).

The 7Gb/s was Cerny explaining that due to the difference in design between Sony solution and the standard PCI 4.0 design a 7.0Gb/s would likely be needed to reach the 5.5Gb/s on PS5 due to the overhead of the controler on PS5 having to match the lack of the 6 levels of priority.
