What's that "insane storage solution" they are all talking about? A M.2 SSD? 2 M.2 SSDs in some sort of RAID0? I'd really be surprised if it was anything more advanced.
what ever it is, apparently it runs at 9GB/sec which is much higher than the current limitation on NVMEs. only problem is, how many seconds of gameplay do you get streaming that? fucking geniuses i tell you
Regarding loading and streaming, though, Sweeney says that the PlayStation 5's SSD architecture is "god-tier" and "pretty far ahead of PCs," but that you should still get "awesome performance" with an NVMe SSD, which I'm using. One thing is for sure: If you haven't already, it's time to ditch HDDs, which Sweeney doesn't expect anyone to load games from in the near future.
This was true back then. A lot of people having 4GB of RAM and a 32bit OS.

Hmmm... then my guess is it's some sort of M.2 SSD cluster with a DDR4 RAM buffer. Or more direct PCIe lanes to the CPU, afaik our current M.2 drives only use 4 lanes. In any case, it will not be "revolushionary" or "god-tier"

PCIe 4.0, custom made. You have to take into account cost always. This is meant to be an affordable entertainment device and they packed something top of the line in it.

Finally announced, the PS5 has RAD's Kraken decompressor (from Oodle) implemented in hardware, able to decode 5 GB/s data. (Typically 8-9 GB/s output, capped at at most 22 GB/s.)

When you take cost into account, then yes, it is insane. They put something top of the line in it, while keeping cost of the entire console low (likely $500).
This doesn't mean games will run bad on PCs. For one games are multiplatform, they will target the Xbox too.
But the PS5 is meant to last for several years in comparison to a PC that you can upgrade it whenever you feel the need, so it's great they put something so fast in it, so that it can age gracefully.

Alright consolitis, thanks for the very insightful post. That sounds very plausible. And I've stumbled over Oodle before, some of the better optimized games use it for their netcode, apparently it's quite advanced stuff, way more efficient than Googles protobuff. Baking that into the hardware is clever indeed.
It's an M2, with crazy high thruput I guess.
I think a lot also goes not into the actual ssd but the way low level ps5 software internals handle stuff like streaming compression and all. Custom ssd controller chip and custom receiver on the ps5 motherboard probably go a long way too.

They should have used a more powerful GPU instead.
GPU (and to a lesser extent CPU) is most important when it comes to gaming performance, not some "super SSD".
Consoles will always be ~30 FPS it seems.. PS4 Pro is 25-30 FPS for the best looking games, no change from PS3.
It's not too strange, its because graphics still "sells" the game more than high FPS output, and you can never have both really... because if you decide to go with 60 FPS you'll obviously have to sacrifice graphics, and you will then compete (graphically) against the games that runs at 30 FPS (and which can therefore look a lot better).
For PC we don't really have this because in PC games we have something called "settings". Something which would be truly Next-Gen would be to introduce this "mysterious" thing for consoles
Gotta love how you can't e.g turn music off in some games and similar idiotic things.. i remember particularly annoying music in a certain Nintendo game where i just decided to play the game without sound..

CPU and GPU will be upgraded with the PS5 Pro refresh once they become dated.
They couldn't really introduce a fast SSD with the PS5 Pro refresh and start having games designed with it in mind, because these games would still need to run on original model PS5.
So it's good they introduced this now and do CPU and GPU upgrades with PS5 Pro instead, and I expect we'll see some cool PS5 exclusives that make good use of it, eventually.

Microsoft is doing the same, using de/compression baked into the silicon, with Xbox Series X. The drive can perform 2.4GB/s but with this tech it can do 6GB/s.
The form factor is cute, the 2.4GB/s of guaranteed throughput is impressive, but it's the software APIs and custom hardware built into the SoC that deliver what Microsoft believes to be a revolution - a new way of using storage to augment memory (an area where no platform holder will be able to deliver a more traditional generational leap). The idea, in basic terms at least, is pretty straightforward - the game package that sits on storage essentially becomes extended memory, allowing 100GB of game assets stored on the SSD to be instantly accessible by the developer. It's a system that Microsoft calls the Velocity Architecture and the SSD itself is just one part of the system.
"Our second component is a high-speed hardware decompression block that can deliver over 6GB/s," reveals Andrew Goossen. "This is a dedicated silicon block that offloads decompression work from the CPU and is matched to the SSD so that decompression is never a bottleneck. The decompression hardware supports Zlib for general data and a new compression [system] called BCPack that is tailored to the GPU textures that typically comprise the vast majority of a game's package size."
The final component in the triumvirate is an extension to DirectX - DirectStorage - a necessary upgrade bearing in mind that existing file I/O protocols are knocking on for 30 years old, and in their current form would require two Zen CPU cores simply to cover the overhead, which DirectStorage reduces to just one tenth of single core.
"Plus it has other benefits," enthuses Andrew Goossen. "It's less latent and it saves a ton of CPU. With the best competitive solution, we found doing decompression software to match the SSD rate would have consumed three Zen 2 CPU cores. When you add in the IO CPU overhead, that's another two cores. So the resulting workload would have completely consumed five Zen 2 CPU cores when now it only takes a tenth of a CPU core. So in other words, to equal the performance of a Series X at its full IO rate, you would need to build a PC with 13 Zen 2 cores. That's seven cores dedicated for the game: one for Windows and shell and five for the IO and decompression overhead."

Pretty nice that it won't need normal maps, halves the amount of textures needed + they can be time consuming to make too...
so many games have f'ed up normal maps too because they were in a rush so they weren't tested properly and lighting is inverted or something else is off... tons of such textures in Bethesda's and Obsidian's games..

What already is easily achievable on PC in this regard and without any hassle ("13 Zen 2 cores")is more than enough for games. Consoles were fucked when it comes to this yes. Now they are not. Big deal! lol
I suspect they are trying to push this narrative for one reason only- they have nothing else against PCs

RAW transfer rate isnt anything. PS5 achieves on their version of PCIeX3 (1 year ago since unveil in march, since then they've updated it seems) up to 9-8 as well through Kraken-compression and custom super-engineered IO logic for storage data trasfer. Arguably, PCIeX4 is just a carton incremental upgrade, what Sony has for PS5 with their custom HW is actual evolution.
"It will come to PC"
Yeah, about that. With massive pain and veeery slowly due to the fact how PC ecosystem is developed to always target the lowest denominator. There always will be people with HDDs or SATA SSDs and that is piece of the market which means any kind of software products (I include games and other products as well) will be always trying to cover whole market and often the cost of developing support for optional features like super-fast niche storage systems can be too high to bother, thus, we gonna have to wait 20 or so years before it will take off properly.
"We can just put SSD;s in RAID 0-1-2-3-4-999 "
Yeah, no, Linus recently had a server with about 32 SSDs in RAID and his 32 core CPU couldnt even keep up processing that much data. WHOLE CPU dedicated just to that. In comparison, PS5 wastes almost no CPU cycles on that, it is handled on-chip.
Imagine PC platform that dont just upgrade their raw tech liek PCIeX every 2 or so years but actually addressing all these latency bottlenecks and revamping whole storage system to the point it is no longer 10 000x slower than RAM but just in the range of hundreds.
Coreteks has some good surface summary about it, I timespamped where it starts (16:55):

We've never seen anything even remotely like this in games (amount of triangles) so it would be idiotic to say it's not extremely impressive... The leap is absolutely gigantic in terms of graphical detail possible, it's the biggest graphical leap we've had for 3D games. The engine being able to push models and environment of this detail will automatically solve a lot of previous issues too, like lighting..
Like always it's good to be skeptical since it's just tech-demo-"game" and not a game with AI etc + the fact we've never had a 100% perfect 3D engine, so it's idiotic to believe this engine will not have its share of problems.
The technologies that matter become part of all games' pipelines, e.g. CSM, PBR, etc. and not just 1 engine.
If we start hearing that other engines use similar tech, then this is definitely going to be a thing then.

They will obviously need to catch up, or they're completely out, like i said, the leap is immense and a total game changer.. Such thing can happen, but probably only for a very short amount of time where everyone will chose one engine over all others.
We'll see. I rarely get excited these days for graphics, can't remember the last time, but this is (potentially) really big.
