Silicon Motion has introduced its latest SM2508 Gen5 SSD controller, claiming it to be the most power-efficient Gen5 SSD controller in its class. This new controller, built using TSMC’s 6nm EUV process node, achieves a significant 50% reduction in power consumption compared to controllers manufactured using the 12nm process. The company highlights that the entire SSD operates with less than 7W of power, making the SM2508 1.7 times more power efficient than Gen4 SSDs and up to 70% better than competing Gen5 SSDs available in the market.
Silicon Motion’s new SM2508 Gen5 SSD is a high-performance, low-power PCIe Gen5 x4 NVMe 2.0 SSD controller specifically designed for AI PCs, catering to the growing trend of Copilot+ PCs. The controller supports up to eight NAND channels with a maximum speed of 3600MT/s per channel, resulting in read and write performance of up to 14.5GB/sec and 13.6GB/sec, respectively. This impressive performance is achieved while maintaining a power consumption of approximately 3W.
Silicon Motion’s in-house 8th-generation NANDXtrend technology plays a crucial role in maximizing the SM2508’s performance and power efficiency. This technology features an on-disk training algorithm that optimizes ECC timing, leading to enhanced performance and power savings. Moreover, it ensures compatibility with the latest 3D TLC/QLD NAND technologies, enabling higher data density and meeting the evolving demands of next-generation AI PCs.
Nelson Duann, Silicon Motion’s Senior VP of Client & Automotive Storage Business, stated that SSD storage solutions must adapt to the evolving challenges posed by AI applications, which require data efficiency and high-performance models. He emphasized that the SM2508 Gen5 SSD controller, with its exceptional power efficiency, perfectly addresses the unique requirements of today’s AI-capable PCs. By delivering high performance and power efficiency, the SM2508 is designed to meet the evolving standards of tomorrow’s AI PC landscape.
