The enterprise SSD market experienced significant growth in Q3 2025. According to the latest research by TrendForce, driven by the rapid expansion of AI demand from training to inference applications and the simultaneous infrastructure buildup by North American cloud service providers (CSPs) for both AI and general-purpose servers, enterprise SSD shipments and prices rose sharply. Combined revenue of the top five brands grew 28% quarter-over-quarter (QoQ) to $6.54 billion, marking a yearly high.
TrendForce noted that market sentiment shifted from "recovery" to "material hoarding" in Q4, as NAND Flash suppliers adopted a cautious approach to capacity expansion due to historical market volatility. This has led to enterprise SSD supply growth lagging far behind demand. To avoid delays in costly AI server deployments, CSP buyers are actively building inventories. Under this supply-constrained environment, Q4 enterprise SSD contract prices are projected to rise over 25% QoQ, with industry revenue expected to hit another record high.
**Key Supplier Performance in Q3:** - **Samsung**: The market leader capitalized on rebounding demand for general-purpose servers, particularly with Intel’s Ice Lake platform remaining dominant. Leveraging its comprehensive TLC SSD portfolio, Samsung secured substantial orders for mature-node SSDs, driving a 28.6% QoQ revenue increase to $2.44 billion. - **SK Group** (including SK hynix and Solidigm): Despite only modest growth in high-capacity product shipments, the group saw strong overall demand for TLC SSDs in servers, lifting revenue by 27.3% QoQ to $1.86 billion, securing second place. - **Micron**: The company strengthened its PCIe SSD competitiveness in recent years, expanding its client base. Q3 shipments continued to climb, pushing revenue up 26.3% QoQ to $991 million, ranking third. - **Kioxia**: The fourth-place player achieved the highest growth among major suppliers, with revenue jumping over 30% QoQ to $978 million. Unlike peers focused solely on finished SSDs, Kioxia’s flexible strategy includes supplying enterprise-grade NAND flash components to CSPs with in-house development capabilities, reinforcing its role as a key supplier. - **SanDisk**: Revenue reached $269 million in Q3. With its 218-layer products ramping up and robust QLC demand, the company is poised for stronger revenue growth in 2026 compared to competitors.
