Samsung widens Nvidia Vera Rubin memory play with PCIe 6.0 eSSD

Samsung's move into PCIe 6.0 eSSDs signals a strategic pivot from HBM-centric AI memory to full-stack infrastructure dominance. This triggers a cascade: controller vendors like Marvell must accelerate firmware and thermal design innovations to meet sub-100μs latency demands. Amid tightening U.S.-EU export controls on AI hardware, Samsung faces heightened compliance risks in its supply chain across Korea and Taiwan, China, potentially inflating operational costs. Rivals SK hynix and Kioxia will likely fast-track PCIe 6.0 rollouts, while YMTC could exploit cost advantages in mid-tier segments. Within 18 months, the race to eliminate I/O bottlenecks will cement U.3/E3.S as de facto standards—making enterprise SSDs the new battleground for AI compute economics. Control storage bandwidth, control the stack.
