Silicon Motion Technology Corporation ("Silicon Motion"), a global leader in designing and marketing NAND flash controllers for solid-state storage devices, today 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 Gen 5 DRAM-less controller offering industry-leading 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.

SM2504XT Delivers High Performance and Low Power for AI-Driven Client SSDs
Built on TSMC's 6 nm 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 5 W. Compared to the previous generation, it achieves an 11% gain on performance per watt and sets a new standard for power efficiency among PCIe Gen 5 client SSD controllers.



Supporting PCIe Gen 5 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 to increase sequential read speed by 15%, 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 4,000 MB/s, optimized 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.

"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 Gen 5 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 will also showcase a broad portfolio of controller solutions at COMPUTEX 2025 targeting markets including automotive, AI smartphones, 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.
