Silicon Motion showcases next gen controllers

SM2504XT delivers high performance and low power for AI-driven client SSDs

Built on TSMC’s 6nm process, the SM2504XT delivers up to 11.5GB/s sequential read and while consuming under 5W. Compared to the previous generation, it achieves an 11% performance gain per watt and sets a new standard for power efficiency among PCIe Gen5 client SSD controllers.

Supporting PCIe Gen5 x4 and NVMe 2.0, the controller is ideal for DRAM-less SSDs in AI PCs, notebooks, and gaming systems. It also incorporates Separate Command Address (SCA) architecture for reduced latency, and supports the latest 3D TLC and QLC NAND – meeting the growing demand for cost-effective, high-performance, and energy-efficient SSD SM2324 delivers integrated simplicity for next-gen portable SSDs.

The SM2324 single-chip portable SSD controller combines native USB4 support with built-in power delivery controller. Delivering sequential read/write speeds of up to 4,000MB/s, optimised for 3D TLC and QLC NAND, the SM2324 supports storage capacities of up to 32TB. Its single-chip architecture reduces BOM cost and simplifies design, accelerating time-to-market for OEMs building compact, high-speed portable drives.

“At Silicon Motion, we’re focused on delivering SSD controller solutions that lead in both performance and power efficiency,” said Nelson Duann, Senior VP of Client & Automotive Storage Business at Silicon Motion. “With the SM2504XT, we’re setting a new benchmark for PCIe Gen5 client SSDs with unmatched performance per watt, while the SM2324 redefines portable storage with a fully integrated single-chip USB4 solution. These technologies reflect our commitment to helping customers build faster, smaller, and more efficient SSDs for next-generation applications.”

In addition to its latest client and portable SSD controllers, Silicon Motion also showcase a broad portfolio of controller solutions targeting markets including automotive, AI smartphones, datacentre/enterprise SSDs, and high-performance display interfaces. These offerings support a wide range of AI-driven applications, from intelligent vehicles and Edge devices to Cloud infrastructure and immersive user experiences.
