PS5 and Xbox Series X SSDs will surpass PC NVMe

It seems that both SONY and Microsoft are putting all the meat on the grill with these new consoles and proof of this has been the frequent performance samples that have been shown to the public. SONY specifically launched a kind of demo where you could see the loading time and on-site performance of a game between the new PS5 and PS4 Pro.

The difference in performance offered no doubts about the winner, but about the technology used, since we talked about 10 times the performance between these consoles. According to sources, the answer is in a technology called Software-Defined Flash or SDF, which allows an NMVe SSD to achieve performance rates not seen in the consumer PC sector.

SDF: a technology for SSDs in cloud services

SDF was created to meet the needs of large cloud service operators, such as server farms, scalable data centers, communications infrastructure and the like.

This technology gives full access to the storage of NAND Flash in solid state units, which allows higher I / O speeds due to the greater control it implies and at the same time reduces wear and tear in the correction of data and random readings or writes.

The first tests that were done there in 2014 showed a performance of up to 3 times higher in I / O, which triggered the interest of the rest of companies for this technology. Five years later, all large companies have similar technology, as developers can access in a more personalized way everything that happens in these SSDs.

An access of this type promotes that developers can more optimally exchange information between CPU, GPU, SSD and RAM or even skip some intermediate step through a system of RAMCaché increase performance between for example the VRAM and system RAM, without having to go almost through the SSD.

SONY and Microsoft already had similar solutions to SDF
