I'm not sure if a suitable equivalent exists on the market as of now. Cerny said that "At the time of my Wired interview, the ones on PC had 3.5 GB/s". And that the ones they're testing these days "come in at 4 or 5 GB/s".
The one you linked seems to be "4950MB/s read, 4250MB/s"?

PC has had faster SSD's before Cerny made that "dodgy" claim.
PC can RAID. Nor did Cerny mention form factor or pricing or so forth.

The one I linked to... Actually does 5.22GB/s. Are we really splitting hairs over 0.28GB/s?


Besides, my point of contention isn't with Cerny... It's with the Poster making a blind general statement that PC SSD's cannot match the Playstation 5's when the PC does in-fact have SSD's that wipe the floor with what the Playstation 5 has.

Not only that but he said that a commercial M2 drive would require "a little more speed to make up for the issues that arise from the different approach". 
Referring to how the commercial drive would only have 2 true priority levels, while the one in PS5 will have 6.
It would also need to physically fit in the PS5, since there's no standard for the height of the drive.

So it sounds like we'll need to wait and see which drive they say will work properly.

Well. "He" needs to backup that assertion with evidence.

Because a real-world benchmark with real-world performance numbers is real-world speed and thus already accounts for "issues" due to the different approach.

And no... It doesn't need to fit into the PS5, we are talking SSD speed comparisons here, not fitting a PC drive into a PS5.

Besides... You also have drives like the Kioxia SSD's which can do 6.9GB/s...

You can double that to 13.8GB/s easily enough via RAID.

And if you don't like that brand... The Samsung PM1725a will deliver over 6GB/s of sequential reads.

I can keep going... But I think I have made my point. :P

From what he said a PCI4.0 7Gb/s would be needed to match because of the controllers and priority layers.

Good news. That's possible on PC.

I don't know if you're referring to something I didn't read. But I only read that Pemalite said that CuCabeludo was incorrect about it not existing on the market yet.
That's not the same as saying Sony are lying, because CuCabeludo could have misinterpreted something.

During the last 6 months or so he was adamant that the SDD in PS5 wouldn't be something faster than on PC (at the time). But that isn't really much important.

RAID is possible even in notebooks. So... You are clasping at straws there.

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.

Intrinsic said:

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...
