And? Just because it's propriety doesn't mean squat.
The tech industry is littered with the bones of propriety technologies that failed... Case in point, Sony Memory Stick format.
https://en.wikipedia.org/wiki/Memory_Stick

I do have to ask, what is so propriety about it? Feel free to elaborate, just so I can understand your level of understanding on this specific topic.

I was responding to your point on a Sony patent which mentioned SRAM in the SSD... As if it was something new and novel and never seen before which is false.
So yes, SRAM is very much the argument.

What combination and solution to be precise? Fact is we don't know what implementation the Playstation 5 is going to go with... Because the hardware hasn't been revealed in any detailed breakdown. A patent doesn't mean squat.

Have you seen the Playstation 5 in person? Have you seen a tech outlet tear apart a Playstation 5 and shown us the dedicated CPU and cache for the SSD? Or are you just asserting something as factual, without knowing the facts?

And are you sure that PC SSD controllers don't have a dedicated CPU and Cache? Or is that another false assertion?

I never stated the PC has the same technology, nor did I state the PC requires the same technology to equal or better the implementation Sony goes with, making this a goal-post shifting logical fallacy.

The PC can and does have SSD implementations that will wipe the floor with the Playstation 5 because power, cost and size is not a factor.

And yet. The PC can still beat the Playstation 4 in terms of performance, because it doesn't have cost, power, size limitations.

In saying that, new APU architectures (I.E. Vega) have a plethora of technologies that conserve DRAM bandwidth... Such as Delta Colour Compression, Primitive Discard, Draw Stream Binning Rasterization, Primitive Shaders, Index Cache, Improved Culling and more... Meaning it does more work per unit of bandwidth than the Playstation 4.
Once Renoire drops with DDR4 DRAM speeds of 4266mhz, things will get really interesting.

It proves absolutely nothing as you don't know if it's going to be in the hardware being released into the market.

Cerny's statements in regards to the SSD doesn't trump the fact that overall, the PC can have faster SSD implementations than a console could ever possibly have as it's not restricted by cost, power or size... There is this little known technology known as "RAID" after-all, which allows multiple drives to work together to bolster reliability and/or performance.

It's super mega squat.  Proprietary means it's only available for Sony .  " AVAILABLE FOR SONY " their device or their own benefit (they can sell it or use on other company that pay their design or concept) This is the reason WHY PATENT EXIST. Will it be used at real world??? Probably but that's not the point here, they have the tech to backup my claim. Pend of argument. 

SRAM in this world is not new but implemented for SSD for cheap price , affordable ready available for use to the mass and costume (build specific number of memories that SONY needs  for playstation requirement)   So they don't need to pay another unnecessary cost. 

Just read this , dont be lazy https://www.resetera.com/threads/ps5-a-patent-dive-into-what-might-be-the-tech-behind-sonys-ssd-customisations-technical.118587/

NO IT's NOT, PC are build for every other purpose that making it more expensive while consoles it consist only for gaming . SMH 

I never said PS4 can beat a high end GPU. i am saying they solution is smarter by cutting cost to achieve the same result on PC with more efficiency in terms, game development, performance impact , lower TDP, and the graphic  effect and price  . And it did 

You seem hating any progress Sony has or hate when SONy as a hardware company based , also silicon, and tech company making any progress do you?  

It proves my opinion , regarding the first patent. It proves that they have the solution, regarding it will coming to PS5 or not is not the main problem here. They can and they have the solution.

You were asking " did SONY can have a fast SSD on the market that can beat current SSD on the "GAMING " market Yes they can, by implementing the tech they have. 

You seems have an identical crisis as PC gamer if getting offended by consoles progression. SMH

EDIT ; https://www.techradar.com/reviews/samsung-970-evo-plus

below is samsung spec of read and write 

This is Sony propetry SSD tech that possibly the solution for PS5

Sony has 10 GB read and write, it's fast even when you comparing it to Samsung 970 evo 

The SSD tech could be great, yet not be anything unique and special, other than the combination in a proprietary cartridge.

I wouldn't be surprised if SNY assumed the general public is too incompetent to install a typical SSD stick, and so housing it in a cartridge would make sense. Why not just use a typical 2.5" SSD then? Maybe they found that few people bothered upgrading their internal HDD on PS4 due to 'being too complex'. Maybe PS wants to have an option for a clean looking gaming center without requiring an external storage drive.

If by chance the SSD space on PS5 is going to be seen as borderline enough, they may plan on selling a boat load of SSD upgrades or expansions. This wouldn't be any different than in the past where console companies would sell memory expansion packs or larger memory cards themselves. This could be a way to keep the launch price down at a more reasonable level, or it could be a way to make back some of any losses on the console, or make extra on top.

Then again, maybe it's a cart for a PS Portable, whatever games it may end up playing.

You will not find any Nvme like this on the market 

EDIT: why would Sony bothered making a patent for it or even customize it, if it's not to cut the cost , making it more  accessible or make it even faster. 

If sony using normal Nvme for PS5  they will not make any patent, or making any statement.
