If anything thing is holding back Xbox 1st party games, its PC and Xbox One. Most PC gamers use SATA SSDs or HDDs (and Xbox One has a slow HDD too.)
Because all Xbox Studios games are PC games, they can't build a SSD for their console that would make PC ports impossible. They have to hold back in cost for Series S too sure, but they also have to consider PCs for all their games. Unlike Sony.

They can always make SSDs a requirement but they would lose a ton of sales and gamepass subscriptions if they did that.

Well yes because there are rumors of a delay. It certainly fooled me.

So I'm pretty sure this is drawing shows the differences between how the Xbox Series X and PS5 SSD's are set up. Hopefully this helps anyone who doesnt get the whole lanes/channels thing.
Of course no, its not to scale or too serious, just to show how the internal interfaces and external interfaces compare.
And yes, I'm assuming the XSX uses 4 channels and 4 nand dies. It could be a bit different, like maybe 2 or 8 nand dies.

The only disadvantage that I see with the PS5s I/O is that the chips are smaller.
I don't know if this will cause any issues though.

You guys should jump on a plane together on flight simulator and talk things out✈✈✈
Is that a way of asking us to come pick you up?
I detect a hint
And flight sim can suck my balls

The XSX seems to just be using 2 or 4 large density NAND dies. I doubt they are using 16 NAND dies in a drive this small. They are probably just buying larger density chips.
Their SSD looks like its 22 x 30 mm (like a M.2). It proably has 4 internal channels and then uses 2 lanes of PCIe Gen 4.
Looks like both are the same size, speed, and density. Probably both made by Seagate.
They are both using 4 lanes, as shown on all graphs. Seen your other post as well. Let's not forget it's a read/write process, so you need them working in parallel?

It just means the PS5 has 825 GB instead of 1 TB. So thats a bit less storage. Thats all.

Nope. Xbox Series X only uses 2 lanes of PCIe Gen 4 for its SSD. It uses 2 more lanes for the Expansion Card. 2 lanes allows for up to 4 GB/s, so they don't need anymore than 2 per drive.
Seagate also confirms the Expansion Card only uses 2 lanes of PCIe Gen 4.

And consoles dont do much writing, only when installing games or patches. Saving game, etc.

That's pretty shocking! Thanks for the details.

Its all they need. 2.4 GB/s. Why use more than 2 lanes if it can allow for up to 4 GB/s?
Sony needs 4 lanes for their SSD because its more than twice as fast.

This makes me feel so weird, like if this was the case for PS5 the level of FUD and videos talking about "VelocityArchitecture" could be massive...

So how is SFS supposed to make up the difference?
It's what some people are saying and I don't really understand it.
TrippleA345

Right. They do not need more than 2 PCI Lanes
Decompression and all the other stuff happens after it's already transferred over PCIe to RAM.

So SFS is really just used to save up space on Ram not to decrease the data that's decompressed.
jose4gg

I read those specs from day one, but I've been doing what Yosp tell them to do..."Let them dream"
Ah. You're talking about residency map.
SFS will just make less requests for data blocks from SSD. I.e. CPU will.
MasterCornholio

"Let them dream"
Well they were confusing me because they made it seem it would close the I/I gap when all it does is save space on the ram. Which the PS5 does with it's I/O because it only needs to store the next second or two of data instead of double that amount.
Yup. That's pretty correct.
TrippleA345

correct
hard to say. depends how it works/ how its implemented
MasterCornholio

I can't imagine decompressing half of a texture from an SSD if that makes any sense.
I'm assuming you decompress the whole thing but you only store what you need in ram.

Yeah i understand, but the Software and Computer Industry surprise me every time what is Possible. In my studies there were also some things in computer science that surprised me, but as you say, unlikely that compressed data can be partially loaded for sfs.

Microsoft isn't really good creating UI in any of their products I'm happy that's the new UI.

Yep, the I/O of the PS5 is exactly what we been hearing, is a generation ahead of MS...
They will use tex blocks. Probably 64K in size.
Probably will know offsets without decompression.
I think PS5 I/O is generation ahead of anything that exists on PC market.
At least for the 99% read workloads.

Generalization: Ps5 i/o (unit) is considerably more powerful/faster than any other gaming system currently available.
Because, for example, the DMA Controller in the I/O unit isnt new technology. Thats why is not "generation ahead", its just playing in his own league. Nothing can compet against it.

Nothing is making up that difference. The hardware capability is maxed at 2.4 uncompressed, 4.8 compressed.

that’s an easy answer: It doesn’t.
No software optimization is going to close a gap of 3.1 GB/s.

The console is definitely on production, the games though.....

SFS makes up the difference because you can use it to only load a specific part of a specific LOD. Meaning instead of loading a whole 10mb of texture data you might only need to load 2mb. Microsoft is saying due to only needing to load 40% of the textures their console would actually outperform a SSD that's 2.5x but has no SFS.
If anyone thinks they are wrong feel free to say why.

I'm not convinced that the PS5 SSD will cost THAT much more than the XSX SSD. It all depends on how much more costly the 12 channels and 2 extra lanes of PCIe 4 are.
I assume Sony went with 12 channels to hit their speed goal without having to buy faster NAND, so it must cost less relatively to add more channels than to buy faster flash dies.
(Just like Microsoft chose to use a wider bus for their memory, instead of buying faster GDDR6.)

Did anyone else see that the Xbox One can't even run Tony Hawk Pro Skater 1/2 remake at a consistent 1080p? Had to use dynamic res w/ average of 900p. For a PS1 game remaster.
No wonder Halo looked rough, the developers are fucked for having to make games run on that system.
