Marketing BS. They may have optimized resource decoding. I have seen games that read from NVMe only 400MB/s in loading due to unrealistic game file compression in times of fast storage drives.
In other words, I expect that they had to rewrite loading procedure where CPU was the bottleneck. Especially when console has its own storage compression in place.
But it is not like game will load assets from storage on per frame basis. They load their megatextures, high polygon models and will manipulate those on per frame basis. There is no reason to reload same asset over and over again from relatively slow storage.
They may have enabled faster caching of new assets which means better texture LOD for newly appearing assets. It may have even enabled them to get rid of very low resolution LODs. And all that is good.
But what they posted is basically marketing for PS5.

"the PlayStation 5 SSD" 😀:D:D:D
there's no such thing.
can't wait for ps5 to get disected to see how many components are actually made by sony.

there's no such think as playstation ssd.
sony doesn't own a ssd making factory. it will be a third party, already existing SSD...
this sounds very much like the marketing bs they pulled before when they presented watchdogs and division running on ps4 with amazing graphics only to get a highly graphical downgrade on release because the ps4 couldn't handle that.
and the fact that it was downgraded on the PC too tells us sony pays good.

Guys: most of you are wrong. Now, I got more love for you than ever before right now, with this human malware killin' us all off, but, the Playstation is not a Microsoft console, just using whatever pre-existing parts are on the shelves...
This is custom silicon, as close to being bolted onto the CPU than you can ever get.
Did any of you actually think they just use what you or I would use? Seriously?
Watch the deep dive on the tech - it breaks it down as follows: the SSD is pure custom silicon. It was most certainly made for them, but designed by them.
Microsoft have lost this round, but as I've said recently to people; this round will be hard faught like the xb360/ps3, but ultimately, PS5 will win...maybe only by one unit sold, but, they will win.

the external NVME drive, has to have the same specifications. Cerny said that in his presentation. Everything will be faster then Microsofts drives. it is up to the developer to impliment certain patches to get it to that speed though. Multiplatform devs will probably go for the same experience, and devs bound to Sony will probably go for the faster option. this makes the most sense.
To bad their event has been cancelled , Horizon 2 will look awesome i imagine (rumoured for appearance)
And i dont think it will be a hard fight. Microsoft has lost it for years. They dont have many exclusives which are system sellers.

As usual, games will matter most. Since consoles are just about games and not about hardware for bragging rights.
Those console will be on the market for at least 3-4 years, and after the first year the hardware will be irrelevant and only games will matter.
As for the ps4 vs xbox one. How much xboxoneX is relevant now?

Dudes and dudettes, please, stop trying to compare PC tech, I/O, file storage, GPU/CPU, memory configurations, compression with PS5 - it is not a PC!
Seeing this crap all over SM right now..."Well, the XXXX SSD drive from XXXX company is currently doing XXX performance, so the performance of PS5 MUST be XXXX as a result!"
No. Just...no. Please stop it.
Custom silicon.
Custom hardware.
The compression alone makes the PS5 win...but everything else just pummels existing tech that us, mere mortals in the land of PC's, currently reside in.
Tim was right: the PS5 has the capability to evolve the PC (tech) market, and if you bare with me on this...don't you think it's time PC architecture was improved?
The master race no more.

Last time i checked ppl played games for FUN, not fast loading times. All of this is pure marketing BS imho. Excuse my french. xD
Loobyluggs
Well, what are you loading?
You can't play games if things are being loaded into memory, and, fast loading times this fast mean that an entire level/map does not have to be loaded, but it can literally stream a level in real-time.
So - no loading of anything, just effecient shunting of data to get it where it's needed most, first.

oh so you already have a PS5 and can tell how it performs in real world? lol
sony outsells MS 4:1 in the past 25y, so much for what ppl like/buy,
completely ignoring the fact that MS didnt even have an equivalent for +5 y AFTER PS1 came out.
in the past, years the main reason ppl where buying MS consoles was because of the games,
but for the past 10-12 month everyone is asking about PS5, not one question about XB, and all say because of the games.
how many games for are "exclusive" to PS for the first year or two? right
and i have yet to see a statement from sony where they say "sony" ssd,
its always other companies, yet ppl bark at sony.
-Tj-
So they had to rewrite it so it will stutter fest faster, gotcha..

I'm not sure how that's marketing.
The SSD is custom built and is it's own separate entity. But that's not the only point. the I/O system is completely different to a PC. It has 12 lanes and DMA controllers that handle everything that goes in and out on an 8 priority system level. PC SSD's have 2. The bottlenecks have been removed because that's where a lot of time was spent. You also forget that Sony's CPU from AMD is custom built using the RDNA2. It's not an off the shelf part. Neither is the GPU.
I'm a PC gamer as well and console gamer. Consoles have the best exclusives end of and 1st party spend that time getting the most out of said hardware. Too many restraints coding for PC using too many different configs.
As for SSD on PC. Yes they are fast for a short while, then get bogged down with I/O speed and that drops down. Look at any benchmark and you can see.
The point your missing is the PS5 SSD with 5.5gb/s raw data and 12lane needs no CPU usage as it's done by co-processors and every PS5 is the same speed.
Microsoft's Texture throughput should be good as well, but will need to use de-compression if trying to compete and it will be slower.
Tim Sweeney isn't the only dev who's been impressed by the machine.
PC will need to change in regard to motherboard's with built in co-processors that do the work. So any SSD gets the same boost.
