AI Server Demand Sent Enterprise SSD Revenue Soaring in Q2 2026

The enterprise-SSD market entered a powerful AI-led upcycle in Q2 2026. Combined revenue for the top five global enterprise-SSD vendors reached approximately $37.59 billion, a 103.6% increase from Q1, according to TrendForce data reported in September. The surge reflected both strong data-center procurement and sharply higher NAND contract prices amid constrained supply. 1

Samsung remained the enterprise-SSD leader

Samsung held the No. 1 position with approximately $14.35 billion in Q2 enterprise-SSD revenue and a 35.1% market share. Its performance was supported by increased shipments of 176-layer QLC SSDs and a higher mix of PCIe 5.0 products. 110

The transition of North American cloud-service providers from PCIe 4.0 to PCIe 5.0 infrastructure also favored Samsung. Its ability to supply both DRAM and NAND gave it an integrated offering for server customers purchasing memory and enterprise SSDs together. 12

Samsung’s leadership in enterprise SSDs did not mean it captured all of the market’s growth. In the broader NAND market, its Q2 revenue rose 70.7% to nearly $23.06 billion, but its share slipped from 31.6% to 29.3% as competitors expanded faster. 28

Micron was the fastest-growing major supplier

Micron delivered the strongest sequential growth among the leading enterprise-SSD vendors. Its Q2 enterprise-SSD revenue rose 126.3% to approximately $6.98 billion, placing it third in the market. 510

Micron’s broader NAND revenue reached $11.85 billion, up 99.2% quarter over quarter, allowing it to overtake Kioxia and move into third place among the top five NAND brands. 23

The company has been directing more production toward high-capacity enterprise SSDs and HBM rather than lower-margin consumer products. Its enterprise-SSD portfolio also benefited from increased shipments of large-capacity 232-layer QLC products, while Micron was described as being at an advanced stage in the development and validation of PCIe 6.0 enterprise SSDs. 1012

SK hynix and Solidigm held second place

SK hynix Group, including Solidigm, ranked second in the Q2 enterprise-SSD market with revenue of more than $8.63 billion. Its sales increased 85.9% sequentially, according to TrendForce-based reporting. 15

The group’s product mix helped it benefit from two parts of the AI-storage cycle: SK hynix was ramping its 321-layer TLC technology, while Solidigm continued to receive strong orders for high-capacity QLC enterprise SSDs. 1012

In the broader NAND market, SK hynix Group generated more than $14.27 billion, up 89.5% from Q1. Its revenue share rose from 17.6% to 18.2%, showing that it grew faster than the market even as Samsung remained the overall leader. 28

Kioxia and SanDisk grew, but at different speeds

Kioxia’s Q2 NAND revenue increased 79.9% to approximately $10.72 billion, supported by high NAND prices and the continued ramp of its BiCS8 products. That growth placed Kioxia fourth in the broader NAND ranking after Micron moved into third. 23

Kioxia also reported approximately $4.64 billion in enterprise-SSD revenue, according to TrendForce-based reporting, after its 218-layer products began gaining certification with leading North American cloud customers and its share of server-brand procurement increased. 24

SanDisk’s broader NAND revenue reached approximately $8.97 billion, up 50.7% sequentially—the slowest growth rate among the five leading NAND brands. Its average selling prices benefited from AI demand, but its bit-shipment momentum was more limited than that of its competitors. 323

The available reporting does not provide a reliable, separate Q2 enterprise-SSD revenue figure for SanDisk. Its NAND revenue should therefore not be presented as an enterprise-SSD total.

AI servers and supply shortages lifted the broader NAND market

The enterprise-SSD boom was part of a much larger NAND recovery. Combined Q2 revenue for the five leading publicly listed NAND brands rose 77% to $68.87 billion. The increase was driven by sustained AI-server demand, especially for enterprise SSDs, alongside significant increases in NAND average selling prices. 239

The market’s unusual strength came from the interaction of demand and supply. Cloud providers continued buying storage for AI infrastructure, while NAND manufacturers faced limited supply and were able to negotiate higher contract prices. Suppliers also prioritized higher-margin enterprise products, improving the mix of revenue and profitability. 210

Why enterprise-SSD demand was expected to stay high in Q3

TrendForce-based forecasts pointed to several sources of continued demand in Q3:

• Wider adoption of generative-AI agent services.
• Ongoing data-center investment by cloud-service providers.
• Large-scale deployment of Nvidia GB-series AI-server racks.

These systems require high-capacity, high-performance storage alongside accelerators and memory. As AI deployments become more extensive, enterprise SSDs are increasingly part of the infrastructure investment rather than a secondary storage purchase. 1417

China represents a potential medium-term shift in the competitive landscape. Higher output from Chinese suppliers and stronger domestic Chinese cloud demand could redirect volumes and alter vendor shares. However, the available reporting does not establish that this production would immediately remove the pricing premium for qualified, high-end enterprise SSDs used in leading AI infrastructure. 17

Memory shortages may persist beyond 2027

The main constraint on the market is not a lack of demand but the time required to add meaningful memory capacity. Micron said tight conditions could persist beyond calendar 2027 because AI-driven demand is expanding across memory segments while structural supply constraints limit how quickly production can grow. The company said supply might improve gradually in 2028, but it did not have a clear view of when supply would fully catch up with demand. 2634

Micron was forecasting approximately $10 billion in fourth-quarter capital expenditure, illustrating the scale of investment required to respond to the shortage. 26 New fabs and related manufacturing capacity cannot be brought online immediately, so capital spending announcements are unlikely to produce rapid relief in NAND, DRAM or HBM pricing.

For AI-infrastructure buyers, the result is a market where storage and memory costs may remain elevated even as server deployments expand. For suppliers, the same shortage creates pricing power and a strong incentive to invest in additional manufacturing, advanced packaging and higher-layer NAND. The key uncertainty is timing: demand is arriving now, while the capacity response will take years.
