At the 2025 Flash Memory Summit, Silicon Motion unveiled the SM8466—its first PCIe 6.0 SSD controller for enterprise storage. Built on TSMC’s 4nm process, it delivers staggering 28 GB/s sequential read speeds and 7 million random IOPS. This doubles PCIe 5.0 bandwidth, targeting AI, cloud, and hyperscale workloads.
Enterprise-Ready Architecture
The SM8466 supports capacities up to 512TB and next-gen 3D TLC/QLC NAND. It complies with NVMe 2.0+ and OCP NVMe SSD 2.5 standards, ensuring compatibility with modern data centers. Key enterprise features include end-to-end data protection, AES-256 encryption, secure boot, and virtualization support (SR-IOV/MPF).
Why This Matters for Data Centers
PCIe 6.0 addresses critical bottlenecks:
- AI training: Accelerates dataset loading
- Real-time analytics: Reduces latency
- Storage density: Maximizes server efficiency
The controller future-proofs infrastructure as Intel/AMD PCIe 6.0 server platforms launch in 2025–2026.
