Computex 2025: Silicon Motion Showcases Next Gen PCIe Gen5 SSD and USB4 Portable SSD Controllers

Silicon Motion Technology Corp. announced that it will showcase its broad portfolio of products including 2 new SSD controllers at Computex 2025, Taipei, Taiwan.

The 1st is the SM2504XT, an ultra-low power PCIe Gen5 DRAM-less controller offering industry-leading performance per watt. The 2nd is the SM2324, a world’s first true single-chip portable SSD controller supporting USB 4 with built-in Power Delivery. Together, these innovations highlight the company’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 6nm process, the SM2504XT delivers up to 11.5GB/s sequential read and 11.0GB/s write speeds, with random IOs reaching up to 1.7M read and 2.0M write – all while consuming under 5W. Compared to the previous-gen, it achieves an 11% gain on performance/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 an industry’s first single-chip portable SSD controller combining native USB 4 support with built-in Power Delivery controller. Delivering sequential RW speeds of up to 4,000MB/s, optimized 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, SVP, client and automotive storage business, 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 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.
