Domestic SSDs welcome the year of explosion, are SSD master players ready?

The past 2019 is a year worth remembering for the process of China’s storage autonomy. This year, Huawei, Hikvision and other companies were included in the “entity list”, which drove the acceleration of China’s independent information infrastructure construction, and the localization of CPU/OS and storage was imminent; With 64-layer 3D NAND Flash, Hefei Changxin mass-produced DDR4 DRAM, Guoke Micro and Loongson launched SSD main control chips equipped with their own CPUs, and domestic storage companies have risen to break the monopoly of foreign manufacturers.

On the one hand, support policies are increasingly strengthened, and on the other hand, product technology is becoming mature. The industry believes that the domestic storage market, especially domestic SSDs, will usher in an explosion in 2020, attacking international manufacturers head-on. The main control and particles are the core components of SSD. Among them, the long-term shortage of particles has been initially solved. For the main control, the “One Picture to Understand the Replacement Rate of ICT Domestic Core Devices” released by Jiweiwang shows that SSD The main control has been able to achieve low-end replacement and move towards the mid-to-high end.

Obviously, the realization of low-end replacement of SSD master is not the ultimate goal. More and more players have joined the SSD master control market, promoting the further maturity of SSD master control. At present, the main domestic SSD control enterprises mainly include Hualan Micro, Lianyun Technology, Guoke Micro, Datang Storage, Deyi Micro, Yixin Technology, Ziguang Derui and Huaxin semiconductor, etc. (Editor’s Note: The companies listed in this article are only Limited to mainland-funded enterprises, and Taiwanese enterprises such as Phison and Huirong are not included for the time being).

This article will make a comprehensive inventory of the basic situation and technical capabilities of these main control enterprises, and try to establish a grade assessment ranking guide for domestic SSD main controllers, in order to make SSD main controllers move to the high-end market as soon as possible and add more glory to the domestic storage market.
