Over the past two years, PCI 4.0 hard disk has been popular on high-end SSDs. Now the 11th generation core desktop also supports PCI 4.0. It is expected that more high-performance SSDs will be launched this year.

Most of Intel's 4.0 and Intel's 4.0 chip manufacturers will choose their own main control group.

A few days ago, Jiangsu Huacun Electronic Technology Co., Ltd. revealed that they have already laid out the market for the main control chips of pci4.0 and pci5.0.

According to Huacun's information, the company started its layout as early as 2018 and put the main R & D force into the main control design of the 4th and 5th generation of pciessds. After four years of R & D, it has entered the final stage of layout design from product specifications, architecture design, IP design and verification, IP module design and verification, and SOC integration, and is expected to import tapeout in the second half of 2021.

Judging from their position, in the second half of this year, the PCI 5.0 master chip will come out, and testing will begin after the completion of the tape,Next year, they may be listed on a small scale, and their goal is very high. They claim to be benchmarking the products of Samsung, Intel and other companies.

The performance of the main controller of PCI 5.0 has not been announced,But in theory, it's twice as much as the 4.0 x4, which is up to 16GB / sIn fact, it is about 15GB / s.

In addition to Huacun, the main control of PCI 5.0 of qunlian, Huirong and other companies is on the way, and the progress is almost the same. It will be possible to be listed in 2022 and popularized in 2023.

The biggest problem for the hard disk of pcie5.0 is the platform. The good news this time is that Intel is much more aggressive towards pcie5.0,12 generations of core alder Lake, 10nm sapphire rapids at the server level will also be supported, while zen4 at amd side is likely to be supported, but it is likely that it will not be launched until next year, so this time Intel may launch pci5.0.
