]]> In addition to self-developed ARM/RISC-V system processors, Russia is also enhancing the localization of SSD master chips. Recently, at Innoprom 2022 International Industry Exhibition, the Russian company Kraftway disclosed its self-developed SSD master chip K1942VK018, which is a PCIe 4.0 master control.

The K1942VK018 main control also uses a different core, not ARM but open-source RISC-V architecture, TSMC 28nm HPC + process foundry, support for 3D MLC, TLC flash memory, the future may also support QLC flash memory, including the Kai Man, Micron and even China Changjiang storage flash memory.

The SSD using this master is produced by GS Nanotech in Russia and supports PCIe 4.0 x4 and NVMe 1.4, with a maximum capacity of 16TB, sequential read and write speeds of over 1500MB/s, and 4K random read and write of 200K and 150K IOPS respectively.

However, as a PCIe 4.0 hard drive, the performance of 1.5GB/s is obviously too low, and the published test results are even lower, with only 1GB/s read and less than 500MB/s write, so there are obviously many problems to solve.
