Institutions: Global Top 5 Enterprise-Class SSD Revenue Quarter-on-Quarter Growth Exceeds 50% in Q4 2025

On March 13, according to TrendForce, a leading market research firm, based on their latest Enterprise SSD industry survey, the fourth quarter of 2025 will see a 51.7% quarter-over-quarter increase in revenue for the top five global Enterprise SSD brands, surpassing $9.9 billion. This growth is driven by the widespread adoption of AI inference applications, large-scale upgrades of general servers, and the transfer effects caused by HDD supply shortages.

Samsung remains the number one, with nearly $3.66 billion in revenue in Q4 2025, a 49.7% increase quarter-over-quarter. Demonstrating its absolute advantage as a vertically integrated leader, Samsung’s strong in-house capabilities in DRAM and NAND Flash have attracted many customers concerned about the stability of Enterprise SSD shipments, especially amid DRAM shortages. Currently, Samsung’s 176-layer QLC Enterprise SSD product line is fully available, with significant volume growth expected in 2026.

The second-largest revenue earner is SK Group (including SK Hynix and Solidigm), which has long focused on high-capacity QLC products. In Q4 2025, Solidigm’s harvest period contributed to the group’s total revenue reaching $3.26 billion, a quarter-over-quarter increase of over 75%, leading the industry in growth rate. Its market share rose to 30.2%. SK Group has developed a clear product roadmap to capitalize on the trend of generative AI moving from training to inference, using technological differentiation to strengthen its position in the Enterprise SSD market.

Micron, in Q4 2025, strategically reduced its consumer-grade product proportion to focus on the higher-margin Enterprise SSD market. Revenue increased by 41.4% quarter-over-quarter to over $1.4 billion, continuing its rapid growth and ranking third. To meet the key KV Cache demands in AI computing, Micron is developing SLC SSDs with high daily write endurance (DWPD), which will become an important product in AI storage.

Kioxia’s revenue in Q4 2025 was $1.16 billion, an 18.9% quarter-over-quarter increase. Although slightly behind competitors, Kioxia is actively planning long-term AI storage strategies, currently focusing on expanding high-speed and high-lifespan product lines to meet future KV Cache and training needs.

SanDisk’s revenue in Q4 2025 reached $440 million, a significant 63.6% increase quarter-over-quarter. Despite the smaller base, this growth is noteworthy. It is expected that SanDisk’s QLC shipment proportion will significantly increase in 2026, with enterprise revenue share rising substantially.

TrendForce states that in 2026, with PCIe 5.0 becoming the mainstream and Enterprise SSD bit shipments increasing markedly, the overall Enterprise SSD market revenue is expected to double. The competition among suppliers will depend not only on stacking more layers in their products but also on who can be the first to offer stable PCIe 6.0 solutions and products optimized for AI workloads.
