Russian supplier Kraftway showed its latest ASIC V1 and ASIC v2SSD using its own controller chip K1942VK018 at Innoprom 2022. This is a PCIe 4.0 controller. Kraftway said the K1942VK018 is the product of TSMC's 28nm HPC+ manufacturing process and has 8 channels.

It also supports ONFI 4.0, soft LDPC decoding, RAID, monitoring, and power management. The K1942VK018 reportedly consumes between 2 and 4 watts of power and can power a variety of SSDs, including half-height/Half-length (HHHL) add-on cards, M.2, and enterprise and Data Center SSD Profile Size (EDSFF) profile sizes.

The Kraftway ASIC V2 uses HHHL demonstration and can accommodate 3D MLC, TLC, and QLC NAND. The company has already verified chips from Kai Xia (formerly Toshiba Memory), Micron, and The Yangtze river storage. In addition, the ASIC V2 uses Russian GS Nanotech memory made exclusively by Meguiar and KioxiaNAND. SSDs use PCIe 4.0×4 ports and have a capacity of 16TB. The sequential read/write performance exceeds 1500 Mbit/s, and the random read/write speed exceeds 200,000 IOPS and 150,000 IOPS respectively. In its demonstration, the ASIC V2 achieved sequential read and write data of up to 971.32Mbps and 476.65Mbps.

The KraftwayASIC V1, on the other hand, focuses on data security features and can accommodate 2D and 3D MLC or pMLC NAND. The M.2 drive is limited to PCIe 2.0×4 connections and has a maximum capacity of 2TB. Vendors rated THE ASIC V1 with sequential read and write speeds of 830 MBps and 680 MBps, respectively. Random performance scales up to 55,000 IOPS for writes and 65,000 IOPS for reads.
