Silicon Motion Technology Corporation showcased its broad portfolio of products, including two new SSD controllers, during COMPUTEX 2025. 

The first is the SM2504XT, an ultra-low power PCIe Gen5 DRAM-less controller, the second is the SM2324, a single-chip portable SSD controller supporting USB4 with built-in Power Delivery.

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

Built on TSMC’s 6nm process, the SM2504XT delivers up to 11.5 GB/s sequential read and 11.0 GB/s write speeds, with random IOPS reaching up to 1.7M read and 2.0M write, all 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 solutions.

SM2324 delivers integrated simplicity for next-gen portable SSDs

The SM2324 is the industry’s first single-chip portable SSD controller combining 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 32 TB. Its single-chip architecture reduces BOM cost and simplifies design, accelerating time-to-market for OEMs building compact, high-speed portable drives.

Nelson Duann, senior VP of client and automotive storage business at Silicon Motion said. “At Silicon Motion, we’re focused on delivering SSD controller solutions that lead in both performance and power efficiency. 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.
