Read the post above carefully. Running Oddle compression gonna make the CPU doing heavier work, so less performance. PS5 have a compression chip.
It's the difference between a DRAMless SSD and an SSD with full DRAM controller.

But it's completely not true though. You must be including the bugs..PS5 is running R&C and TLOU better than a PC for less than a fraction of the price.
Oh I get that. But the oodle is just a compression software for textures. PS5 does have a hardware decompression chip which is bad-ass. 100% agree there. It's just not because of the Oodle is what I'm trying to get at.
Man, a lot of people that wanted to dunk on the PS5’s SSD and I/O but Cerny never talks BS and actually delivers real breakthroughs. Unlike, well, we know who.
At 26:20 major pop in on the high spec pc when jumping through portals, brushed aside 
Cerny is a technical genius. Sony needs to continue to allow him to architect PS consoles until he decides to retire.
A lot of us know better than to conflate the two concepts. There's more to the IO system of the PS5 than just the SSD.
That's probably why some people are confused by the PS5 version still loading faster than PCs with higher specced SSDs.
Technically the GPU usage is low so it's not really the fault of the 4090. Game is CPU/IO bottlenecked.DF is triggered that PS5 runs games better than a 4090?
Of course GPUs are not comparable: the 4090 is way superior. The point is how fast are you going to feed data to the CPU and the GPU: you can have the fastest process in the world, but id the I/O is the bottleneck, you'll have to get in line and wait.
Direct Storage, right now, is not comparable to the PS5 solution, simply becuase it's all software based and does not offload the system: being that a PC or the XBox. As soon as we'll get I/O accelerators with Direct Storage on hardware, THEN we can start talking about comparision. Until then it's either the GPU or the CPU that will be doing the decompressing. Oh, and let's not forget that on PC you have no "direct to GPU memory" functionality: it all goes in the CPU that sends the data to the GPU (so a double use of the PCIe bandwidth)
Guys over at GAF are crying about the PS5 IO advantage..

Can Ratchet and Clank: Rift Apart on PC match - and exceed - the PS5 experience?
We've mentioned before that Ratchet and Clank: Rift Apart is a crucial port for the PC platform, primarily because the game is built from the ground up around the concept of exploiting a games machine with access to a state of the art storage solution, the low-level APIs to get the most out of...

Stop trying to perpetuate disinformation.
Sorry man. I meant the entire I/O system. I corrected my post.
If there was a ps4 version they could have made the portal transitions (between worlds) longer to hide the loading, or just show a loading screen.
The game's visuals could be downgraded close to the level of the previous one in the series.
Direct storage is a software solution… it doesn’t change how the data travel in the hardware.
So yes… the two PC examples are from Direct Storage.
There is no hardware bus from SSD to VRAM… CPU needs to get the data on SSD, copy it on SystemRAM, and after copy it to VRAM.
CPU is the responsible to move the data.
And any data to reach VRAM needs to travel via SystemRAM.
Below 1 and 2 are CPU tasks.
PS5 doesn’t copy data between SystemRAM and VRAM because it is the same pool… and the CPU is not used to travel (copy) the data in the memory because it uses the DMAs inside the I/O complex.

I don't understand why some people thought this could run on a HDD. How could a whole level load that fast on HDD? This never made any sense.
I mean if you got 64GB ram or above you could just page the whole game onto RAM, so it's not really an issue if you are rich. A flex
