Silicon Motion increases sales of SSD controllers amid NAND shortage, but expects NAND shortages to get worse in 2027

Despite ongoing NAND supply shortages, Silicon Motion has seen a significant increase in SSD controller sales, driven by strong demand for high-end products such as PCIe 4.0 and PCIe 5.0 controllers. ... Read original →

The prolonged NAND shortage is accelerating a structural upgrade in storage controller technology. Silicon Motion is capitalizing on surging demand for PCIe 5.0 and enterprise SSDs, shifting capacity toward high-margin products—a move that deepens reliance on TSMC’s 3nm/EUV nodes, turning advanced packaging into a critical bottleneck. Geopolitical tensions are raising compliance costs for Taiwan, China-based suppliers, pushing clients toward supply diversification despite the entrenched ecosystem advantage in UFS 3.1/eMMC. Competitors like Samsung and Western Digital may fast-track in-house controller development, while YMTC could expand its domestic substitution footprint. Between 2026–2027, the NAND crunch will evolve beyond capacity constraints into a systemic risk driven by advanced-node bottlenecks, supply chain fragmentation, and AI-driven data center demand—favoring firms with full-stack firmware-protocol co-optimization capabilities to command pricing power.
