It seems that both SONY and Microsoft are putting all the meat into the blood for these new comforts and the proof of this has been performance samples often shown to the public. SONY has introduced exactly the kind of demo where you can see the loading time and performance of the game site between new PS5 and PS4 Pro
The difference in performance did not give a doubt about the winner, but about the technology used, because we mentioned 10 times the performance between these comforts. According to sources, the answer lies in the technology that is being called Software-defined Software or SDF,
SDF: technology for SSDs in cloud services
SDF was created to meet the needs of major cloud service providers, such as server farms, malicious data centers, telecommunications infrastructure and the like.
This technology provides full access to the storage of NAND Flash on solid state units, which allow for high I / O speed due to large control states and at the same time minimize overlapping and correct data processing and random read or write.
The first test conducted there in 2014 showed a 3-year high performance in I / O, which sparked the excitement of some companies with this technology. After five years, all the big companies have the same technology, as developers can't get in the way of everything that happens with these SSDs.
This type of access improves that developers can exchange extra information between CPU, GPU, SSD and RAM or skip some central step through the program RAMCaché increase performance between example i VRAM and system RAM, without overstating almost SSD.
SONY and Microsoft already had similar solutions to the SDF
The fact is that this is nothing new for any company, as they have been working with their technology and based on the SDF for some time. Intel or Samsung also have similar technology, consistent with rumors of a final offer on the Japanese console.
Samsung executives SCM or Memory Class Memory in data centers and cloud operations, therefore, the software version of your SSDs in the SONY console would not be invalidated. Same situation with Microsoft and its SSD maker (probably Toshiba with its software Denali).
While all of this is happening, at the moment, guess, it is an easy way to limit the performance of the latest SSD units under PCIe 4.0 sold for PC and close to 7 GB / s, a figure that is currently extremely difficult to overcome in one solid unit.
