Yes, I have watched it twice even. Have you?

I prefer not to be too definitive in my statements in case i misinterpreted something. There's nothing as grading as being wrong and acting like you're the only truth holder.

My understanding was that we could add extended storage through a drive bay. I don't think Cerny specifically talked about replacing the existing NVME. For all I know it could be bolted into the mobo, so I don't know. In the past we could always replace hard drives, for whatever that's worth. I think you misinterpreted the "special sauce" SSD. Again, my understanding is that, yes, it's a pretty fast SSD, but what makes it shine is how the system interfaces with it. 12 channel memory controller with 6 priority queues (vs 2 on a regular PC NVME) make it very low latency when you compare it to a typical storage setup. He mentioned as well the usage of Kraken hardware decompression with near lossless quality which means you technically move a lot more data than you typically would uncompressed. I'm patiently waiting to see how it actually translates to real world scenarios, but the UE5 demo got me pretty excited so far.

I don't think this is at all controversial, which is why I'm asking if you have looked into it. You normally have pretty good takes when discussing tech so it gives me some pause when I read you being so defensive about this topic. Have I missed something you're seeing or you just didn't have access to the same info?

So, again, did you actually see Cerny's presentation and got a different take away? Honestly curious.

Do you not see the potential issue if you drop in a commodity PC SSD?

There are fundamental design choices in Sony's I/O layout that may make it incompatible with commodity PC drives.
Microsoft also made a similar decision, hence it's propriety "memory card" approach.

I doubt it's as low latency as Optane or an SLC SSD.

I do indeed and that's a great point. My guess that's exactly the reason why Cerny was being very vague when discussing the expansion of storage and highlighted the certification process "future" drives will need to go to in order to be used. I think that's him opening the door to future SSDs being designed in a way that takes advantage of the ps5 architecture.

As a (also) PC gamer, my biggest hope is that this turns out to be a great architecture design and we could see some benefits of it rolling out to the PC space. I expect this to be a game changer, but am I sure that will be the case? Not yet. The games will be the proof at the end of the day.

As a side note, I'm extremely curious to see if things like DLSS 2.0 (or 3.0) deliver on it's promise and what sort of AMD equivalent will there be, if any.

didnt do DLSS wonders with control?

I'm not using it yet because i'm using a 1080p high refresh rate monitor and gtx 1080 (both on laptop and desktop). I feel the need to upgrade to 4k hdr once prices come down a bit, so DLSS is my only hope for high refresh rates at such high def. Upscaling from 1080 to 4k has been looking pretty good to me, especially since I primarily play FPS games, I shouldn't notice any decreased image quality.

To be fair, we are probably the kind of person who would simply upgrade so we don't actually need to use DLSS anyway.

For those with lower-end rigs/hardware, it can be a good technology to bolster framerates/resolutions.

To me it's just another tool we can use to achieve something if we need it.

You can use DLSS to "upscale" your image to 4k, then super sample it down to 1080P, it's worth giving it a try in your case, might bring some benefits that appeal to you.

Actually I might try it with DLSS 2.0, just need to wait until a game i'm actually playing supports it :)

Gaming laptops :D 4k gaming in slim form factors. I'm ok with that compromise :)

That is the reason Cerny said a regular SSD would probably need 7Gb/s transfer rate to compensate for the lack of 6 priority levels and that they will need to test different SSDs on the market to verify if they will be acceptable. I would expect something along 2021-2022 having some SSDs that could be installed and probably we will have some partnership and official SDD upgrades.

I don't buy a graphics engineer would mistake a video file for an actual demo (running a video file at 40 fps is also bizarre, video files are either 24 fps, 30 fps, or rarely 60 fps). The translated version has the engineers clearly saying the SSD throughput only needs to be in the MB/sec range, not GB/sec. Why in the world would you even bother talking about that over a video file. Sweeney likely has a marketing deal with Sony and doesn't want to rock the boat on that. New AMD GPUs getting outperformed by older Nvidia GPUs in actual practise is nothing new, been happening for ages and Epic already admitted the demo will run fine on a 2070 Super. The PS5 is nothing special GPU wise.
