The PCIe 6.0 standard is officially released: bidirectional speeds up to 256GB/s

For the entire storage industry, the current SSD has reached a fairly high level of performance, especially the master control, and the restriction of SSD continued development is basically the transmission channel, but the improvement of the transmission channel is mainly in the time when the relevant organizations formulate standards and the date when the manufacturer launches related products, and the determination of transmission standards is much faster than the commercialization of the interface, even one to two generations in advance. For example, the fastest commercial interface is pcIe 5.0 interface, but PCIe 6.0 has been officially determined and released by relevant organizations recently.

First of all, the bandwidth, PCIe 6.0 compared to PCIe 5.0 transmission speed continues to double, according to X16 magnification, the highest one-way rate reached 128GB /S, and in fact PCIe supports two-way transmission, that is to say, the maximum speed can reach 256GB/s, if it is assigned to M.2 interface SSD, then according to the speed of x4 to calculate is one-way 32GB/s, this speed has far exceeded the current PCIe 4.0 SSD, It is much higher even than the already exposed PCie 5.0 SSD.

In addition to the higher transmission speed, PCIe 6.0 also supports more signal error correction mechanisms, such as the addition of FEC forward error correction mechanism, so as to ensure the correctness of the signal during transmission, which is very important for some high-performance computing. Of course, PCIe 6.0 also supports backward compatibility, that is to say, the current PCIe 3.0, PCIe 4.0 devices can also be used on the PCIe 6.0 interface, as for the official business time, it is expected that in 2023 will be in the field of high-performance computing and server official commercial use, of course, if you are in the consumer field, then at least have to wait 3-5 years to see the specific interface.
