Damn it, just got 2 M.2 970 EVO Plus. Just one day earlier if I knew it I would wait.

I think our I/O bottleneck is the file system? NTFS is very old.

Phison E16 and only up to 1TB. This was not worth waiting for.
It is sad to see that Samsung stopped developing their in-house controllers.

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.

Will be interesting to see how that API Microsoft was working on and other OS improvements will change the PC situation in regards to not just transfer speeds but other advantages as well but changing some of these might be a long-term gradual improvement without risking breaking stuff or trying to implement some newer model for file system or updating NFTS. (I don't think ReFS is intended for regular consumer systems and might never be intended to replace NTFS?)
Suppose there's a lot to this from how the OS itself currently handles stuff both HDD and SSD wise and then I/O and on the file system side of things, fetching or storing to RAM and then transfer bottlenecks like PCI Express or others although maybe caching critical data to RAM could help at the expense of a bigger increase in RAM requirements possibly even recommended speeds without storing the entire data like some RAM drive.
Might matter more for PS5 exclusives too than multi-platform projects though HDD PC's are still common for storage purposes and even some that only have HDD's so lowest common denominator and how that will work out but getting full effect and taking advantage of these new consoles might also take a bit of time although I can see why developers are really happy getting that bottleneck done with. 😀

I don't think we will get the same real scenario speed as next gen consoles, they are much tightly integrated. Going forward in the future with MCM apu design + on chip memory (HBM) + on chip NAND storage, general purpose computer will be lagging more and more, we need some serious architecture shift and rethink the whole motherboard concept if we want to keep up in the future.

okey ps5 ssd is quicker, but we the master race can just buy more ram? preload the whole thing into ram, now try to beat that with nv storage, finally a reason to get +64gb for gaming

Well i´m thinking about buying a M2 SSD so this is interesting for me. The problem is the size and price because with games becoming bigger and bigger, i don´t know if a 1Tb SSD is going to be future proof...
