Rise of Domestic Enterprise SSD Storage in China (2022) – Technology, Market, and Industry Overview

Enterprise SSD storage in China is experiencing rapid growth, with global data center storage revenue projected to compound at 5.89% from 2022‑2025, and the global SSD market reaching $25.51 billion by 2025, while China’s enterprise SSD market is expected to hit ¥48.9 billion.

The market shift is driven by increasing adoption of PCIe 3.0, 4.0 and emerging 5.0 interfaces, higher performance requirements, and a push for domestic alternatives; in 2021 Chinese SSD controller manufacturers captured 10.33% of global shipments.

SSD technology is categorized by application (consumer, enterprise, military) and differs in interface (SATA, mSATA, M.2, U.2, SAS), bus (SATA, PCIe, SAS) and protocol (AHCI, NVMe, SCSI). Enterprise SSDs favor U.2 and SAS interfaces and NVMe over SATA + AHCI.

Key components of enterprise SSDs include NAND flash (SLC, MLC, TLC, 3D NAND with up to 176 layers), controller chips (handling data transfer, FTL, ECC, wear‑leveling), and firmware/algorithms that act as the SSD’s operating system.

Major players in the supply chain range from integrated manufacturers (e.g., Samsung) to specialized NAND producers (e.g., Changjiang Storage), controller designers (e.g., Marvell, Phison) and domestic firms (e.g., Dapuwi, Yirui Technology) that are advancing Chinese‑made Gen4 SSDs.

Overall, SSDs offer superior performance, lower power consumption, and are progressively replacing HDDs in data centers, with continued market expansion expected at a CAGR above 15%.
