And? Just because it's propriety doesn't mean squat.
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.
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.
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.
And yet. The PC can still beat the Playstation 4 in terms of performance, because it doesn't have cost, power, size limitations.
It proves absolutely nothing as you don't know if it's going to be in the hardware being released into the market.
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.
