Silicon Motion Technology Corporation announced that it will showcase its broad portfolio of products including two new SSD controllers at COMPUTEX 2025. The first is the SM2504XT, an ultra-low power PCIe Gen5 DRAM-less controller offering performance per watt. The second is the SM2324, the world's first true single-chip portable SSD controller supporting USB4 with built-in Power Delivery.

Together, these innovations highlight Silicon Motion's leadership in enabling energy-efficient, high-performance SSD solutions for AI PCs, gaming systems, and portable devices. 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% gain on performance 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. 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, optimized for 3D TLC and Q LC 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. In addition to its latest client and portable SSD controllers, Silicon Motion will also showcase a broad portfolio of controller solutions at COMPUTEX 2025 targeting markets including automotive, AI smart phones, Datacenter/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.
