Huawei eyes AI storage breakthrough with DoB packaging, 245TB SSD roadmap

Huawei’s 245TB SSD roadmap with DoB packaging reflects a strategic pivot to shift AI-driven data demands down to the storage layer. This move will catalyze co-evolution across upstream stacks—from NAND controllers to HBM stacking and silicon photonics—while accelerating China’s domestic controller and advanced packaging capacity. Amid U.S. export controls on high-end memory, Huawei’s approach reduces reliance on American IP but faces yield bottlenecks in high-layer 3D NAND due to restricted equipment access, potentially raising operational costs by 15–20%. Samsung and SK hynix are likely to double down on QLC+ZNS architectures to defend enterprise share, while Western Digital may push OpenFlex to lock in North American cloud partners. Within 18 months, if Huawei integrates a full stack—from custom controllers to foundry and software—it could become the default AI storage choice for Chinese LLM firms, triggering a long-tail decoupling from U.S.-centric ecosystems.
