The Russians, especially in recent months, want to clearly indicate their independence from the West in many areas. One of the most important is electronics, where Russia is a few decades back in relation to the more developed part of the world.

Russians according to your plans intend to start the production of semiconductors in the 90 nm process, and by 2030 – to achieve the possibility of producing chips in 28 nm lithography. According to the servernews.ru portal, the Russian company Kraftway presented SSDs using the PCIe 4.0 interface, which took place during the Innoprom 2022 International Industrial Exhibition in Yekaterinburg.

Two pieces marked as ASIC v1 and ASIC v2 use the proprietary eight-channel controller K1942VK018 produced in 28 nm lithography by a Taiwanese company TSMC. It supports LDPC (Low Density Parity Check) error correction technology, or the common RAID, and is to be characterized by an energy consumption of 2-4 W. The drives are presented in the format of PCIe and M.2 expansion cards.

In turn, the list of supported memory chips includes MLC, TLC and QLC from manufacturers such as Micron, Koxii or YMTC (Yangtze Memory Technologies Co.). Due to the sanctions imposed, it is quite likely that the Chinese YMTC will be the only supplier of memory chips.

—Russian SSD performance.
The Russians also boasted about the results achieved in the very popular benchmark CrystalDiskMark. In theory, sequential reading should exceed 1500 MB / sand the random read / write performance of samples should be around 200K / 150K. Meanwhile, a screenshot of the benchmark shows us sequential read / write at 971.32 MB / s and 476.65 MB / s.

These are still poor results from the days of the first SSDs using the PCIe 3.0 interface. We are talking about 2016and the good SSDs with the PCIe 4.0 interface available on sale easily exceed 5000 MB / s reading and 4,000 MB / s writing. With such performance, the Russian SSD is unlikely to attract special attention, and the subcontractor of TSMC controllers may get prohibition of their export to Russia. This is the same threat as with Russian processors Baikal.
