Rumor: Samsung to release M.2 980 Pro SSD within two months
Samsung would be planning tor release its new M.2 PCI-E 4.0 based 980 Pro SSDs within the next two months, which, and would have higher speeds than the SSD present in the Playstation 5.
This new line of SSDs will be quite a notch faster compared to the current generation, as they are able to maintain sustained reads of up to 6500 MB/s, and writes of up to 5000 MB/s. For comparison, the Playstation 5 SSD has maximum unzipped information readings of 5500 MB/s, so this new Samsung model will outperform it by 1000 MB/s.
The new Samsung 980 Pro will be based on the Phison E16 controller and will use their own MLC Nand Flash memories, reaching these high speeds. Still, they will not be the fastest SSDs on the market: For example, ADATA is preparing SSDs with read speeds above 7000 MB/s, and there are several more companies working on similar products that will reach the limits of the PCI-E connection. 4.0 x4.
It will be interesting to see if developers start optimizing for NVME SSDs on PCs as they get faster and faster, but their difference in load times versus SATA SSDs is almost nil due to lack of I/O optimization. The new consoles, and especially the Xbox Series X that will use a system very similar to Windows 10, could help in this regard, although to know it we will have to wait a little longer until 100% designed games arrive with the new generation in mind.
The 6th generation V-NAND, the latest 3D NAND from Samsung, will be used for NAND flash memory. The number of stacked layers has increased to 128, and not only capacity and access speed but also power efficiency have been improved compared to the previous generation V-NAND.The table below compares speed and power consumption with the previous model 970 EVO Plus. When using the 980 PRO with PCIe 4.0, the power consumption is the highest, but the performance per power is the highest.
Also, when using the 980 PRO with PCIe 3.0, power consumption is greatly reduced and it operates with lower power consumption than the 970 EVO Plus, so it has an advantage in the PCIe 3.0 environment. Three models will be released, 250GB, 500GB and 1TB. The release is scheduled for the second quarter of this year

Is this I/O optimization done at the game's engine or is it related to the OS (Windows)?
but their difference in load times versus SATA SSDs is almost nil due to lack of I/O optimization.
Even if they do to really see improvement in games the i/o needs to be changed a lot or to completely get redesigned this is why the difference between sata ssds and nvme drives on game loading times the difference is tiny especially in comparison to the speed increase

Not only , the files are compressed on your ssd most likely with kraken . Say you want to pull an asset 100mb from the ssd .... The way it works on computer s now is you have to decompress then send it to your ram then send it to the gpu ... From what i got the controller sony uses atm allows em to straight up fetch the asset from the ssd skip all the in between steps and load it directly . We most likely need different /extra controller s on the ssd it self and ofc the os to be aware of it.... I was snob about the ps5 ssd claims till i saw what they did with it !
The way it works right now they will split the install in data chunks say you have the same building in 30 chunks needs to be there on all 30 of em so everytime it gets loaded to the rum..... If all ps5 claims are true you would not need chunks anymore since you can directly access the ssd with out having to threw the hoops to use an asset , look at it is rather interesting when i was looking about it i was constantly saying........owwwwwwh that's why they claim that and this.

IS this the one that rumors had as NVMe in PS5? (QVO)
PS5: NVMe (kraken data) -> Fetch to ASIC for decompress PCIe 4.0 x4 -> Send to shared memory pool at I/O speed between APU and Decompression ASIC = Up to 22GB/s (Typical 9GB/s) according to Sony.
PC: NVMe (kraken data) - > Fetch to CPU for decompress PCIe 4.0 x4 -> Send to System memory at 40~50GB/s or GPU at 64GB/s
PS5's custom NVMe controller with decompression capabilities may or may not deliver Kraken faster than CPU. It depends on how efficient it is and how high clock it has.
(Please note that Cerny stated that their ASIC decompresses data as fast as 9 Zen 2 cores.)
RAD states that Kraken provides 10 times faster decompression than LZMA and 2~3 times faster than zlib. According to benchmarks, it is 10 to 15 times faster than lzma.
One of many situational examples is test with i7-2600K @4,4GHz decompressing on single thread 1,2~1,5GB/s. With SMT one modern core is likely able to decompress over 2GB/s.
While looking for data, I actually found what was Epic talking about when they "rewrote" their code for PS5's storage.
There was rather extensive test of different compressions. Time it took to decode and load game. And beyond certain read and decompression speed UE4 did not actually load any faster.
Basically it did not matter if they got decompressed data at 400MB/s or 800MB/s. Time to load level was practically same.
So Epic did not listen to people over years telling them that there is something wrong. It took storage system capable to deliver magnitude more data per second than was their limit to actually move finger.
This change will help everyone with better storage.

PS5's advantage is not in sustained transfer speeds. It's how the controller, filesystem and OS is able to handle fetch requests, which makes it way faster and more responsive than a PC, in such terms as what a videogame needs to run smoothly. Linus from LTT initially also thought that the PS5 SSD was about raw throughput, and made bold claims that you could already get storage solutions for PC, which was faster than the PS5. But he eventually had to make this apology video, to correct his own false initial assumptions, where he also explains the actual advantages of the PS5 storage architecture:

New Technology File System. Still new, still good.
I'd like to see devs take advantage of these extreme speeds like PS5 is touting, but sadly, it will not be implemented to much benefit. Every time I see people say, "It's in consoles now, so PC will benefit immensely since console is always the focus!" That trickle up (not down;that's insulting) will not be realized. Mark my words.
Even if they do to really see improvement in games the i/o needs to be changed a lot or to completely get redesigned this is why the difference between sata ssds and nvme drives on game loading times the difference is tiny especially in comparison to the speed increase.
