What DapuStor does

DapuStor Corporation is a Chinese enterprise solid-state drive designer and manufacturer founded in April 2016 and headquartered in Shenzhen, Guangdong. The company is publicly listed on the Shanghai Stock Exchange (sse:301666) and employs more than 400 people as of mid-2026, with manufacturing executed in Malaysia and additional global facilities. It sells PCIe Gen3, Gen4, and Gen5 NVMe enterprise SSDs across U.2, E1.S, E3.S, and E3.L form factors, alongside a portfolio of SCM-class drives based on Kioxia XL-Flash and QLC NAND products reaching 245TB per drive, supported by an in-house SSD controller family (DP600/DPU600) and proprietary firmware.

The company's product architecture spans the Haishen series (PCIe 5.0/3.0 mainstream enterprise), the Roealsen5/Roealsen6 series (PCIe 4.0/5.0 capacity and performance), the QLC J5060 and R6060 series for read-intensive hyperscale workloads, the Xlenstor series of storage-class memory SSDs (including the X5900 with sub-20μs latency), and the J5 liquid-cooled SSD line engineered for immersion cooling. Differentiated features include multi-namespace IO balancing scheduling, Flexible Data Placement (FDP), SR-IOV virtualization, transparent compression (up to 3.5x on R6101C), Flash Raid 2.0, advanced power loss protection, and Processing In Storage / computational storage with on-device machine learning. The portfolio is certified by PCI-SIG, UNH-IOL, and the openEuler community, with documented case studies at JD Cloud, China Mobile, ZTE, Capital Online, QNAP, GRAID Technology, and the CRUK Cambridge Institute.

DapuStor generates revenue primarily through unit sales of enterprise SSDs to data centers, telecom operators, and cloud providers, supplemented by customized/ODM engagements (e.g., ZTE liquid-cooled J5 deployment, Dell/Capital Online cloud rendering), and component/firmware licensing tied to its in-house DP600 controllers. Go-to-market blends direct enterprise sales in China with global channel partnerships (Zstor in Europe, Hyperscalers in Australia, APAC and US distributors) and server OEM embedding with Inventec, Advantech, and Western Digital. Pricing is quote-based, multi-year, and varies by capacity, form factor, and PCIe generation; no public list pricing is disclosed.

Emerging players

• ScaleFlux: ScaleFlux specializes in computational storage SSDs that integrate processing into the drive, directly mirroring DapuStor's PIS/computational storage positioning. It targets the same hyperscale and AI database use cases and competes for PCIe Gen5 design wins.
• Biwin Storage (BIWIN): Biwin is a Chinese memory and SSD company expanding into enterprise storage with embedded and PCIe products. It competes in the same China-centric OEM channels and increasingly targets AI/data center customers similar to DapuStor.

Direct peers

• Memblaze: Memblaze is a Chinese enterprise NVMe SSD maker offering PBlaze series drives for hyperscale and AI workloads. As a domestic peer with overlapping China-centric GTM, Memblaze competes most directly with DapuStor for JD Cloud, China Mobile and AI cluster customers.
• Solidigm: Solidigm (SK hynix subsidiary) is a top enterprise SSD vendor with strong QLC and PCIe Gen4/Gen5 offerings (D5-P5430, D5-P5436) aimed at hyperscale and AI data lakes. It directly competes with DapuStor's R6060 245TB QLC drive in AI infrastructure deals.

Broad incumbents

• Micron Technology: Micron is a vertically integrated NAND and DRAM supplier with a major enterprise SSD business (Micron 6500 ION, 7450, 7500). Its high-capacity QLC drives and broad OEM channel make it a direct competitor to DapuStor's R-series and Haishen lines.
• Kioxia: Kioxia is a leading NAND flash and SSD vendor and supplies XL-Flash SCM used in DapuStor's Xlenstor products. Kioxia's enterprise SSDs (CM7, CD8) and SCM efforts compete directly with DapuStor's Xlenstor2/X2900P and Roealsen6 lines.
• Phison Electronics: Phison is a leading fabless SSD controller designer whose controllers power enterprise drives from multiple OEMs and competes architecturally with DapuStor's DP600/DPU600 silicon in third-party SSD designs.
• Samsung Electronics (Memory/SSD): Samsung is the world's largest NAND and SSD manufacturer and offers a comprehensive enterprise NVMe SSD portfolio (PM9A3, PM1743) that competes head-on with DapuStor's Haishen5 and Roealsen series. As an incumbent with captive NAND fabs, Samsung sets pricing benchmarks DapuStor must defend against.

Others

• Marvell Technology: Marvell supplies the Bravera SC5 PCIe 5.0 controller used in DapuStor's Haishen5 platform and is both a key technology partner and adjacent supplier. As a fellow semiconductor vendor, Marvell represents both collaboration and a potential competitive alternative for DapuStor's customers.
• Yangtze Memory Technologies (YMTC): YMTC is a Chinese 3D NAND manufacturer that produces both captive NAND and branded SSDs. While primarily a NAND supplier rather than a direct SSD competitor today, its scale and roadmap influence Chinese enterprise SSD pricing and supply that DapuStor competes against.
