The PCI-Express 5.0 interface will arrive in a few weeks with the next generation of Intel CPUs. It was difficult to get an idea of the interest of this interface when PCI-Express 4.0 is just starting to become a standard for users. A first prototype of SSD with a PCIe 5.0 interface has nevertheless just been presented and the performance provided is spectacular. It is presented by a company whose name, Kioxia, is not really known but which is however the 2nd largest manufacturer of flash memory in the world.

SSD PCIe 5.0: the transition


The product presented is intended for servers, so it will initially arrive in the 2.5-inch EDSFF E3Sformat via the PCI-Express 5.0 x4 interface. At the time of its release, versions of these Gen 5.0 SSDs should range from 1.6TB to 30TB. Consumer versions should arrive soon. The company believes that sometime in 2022, as more and more platforms from AMD and Intel begin to hit the market, the offerings will become more mainstream.

According to data from Kioxia, comparing this prototype with their PCIe 4.0 product showed a 103% increase in read speed (14,000 MB/s) as well as 67% in write (7,000 MB/s). As for the speed of 4K random reading and writing, we are talking about an improvement of 79% / 76% respectively, while the latency of reading and writing has been reduced by 77% and 50% respectively.
