Thanks to the instant seek time of these SSDs, games will not be that big. Do you see those 150GB type games? most of those adjust assets duplicated on the HDD to allow quicker access and ultimately faster reads.

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

But uh, sub 1TB SSD sucks though. Its even suckier is that unless sony actually releases some branded SSDs, we won't be able to buy compatible SSDs for it till sometime next year because what's on the market now isn't as fast. Samsung would probably have a 7GB/s SSD though, but that would probably cost as much as the PS5.

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.
