Silicon Motion Technology Corporation announced SM2508, the best power efficiency PCIe Gen5 NVMe 2.0 client SSD controller for AI PCs and gaming consoles. It's the world's first PCIe Gen5 client SSD controller using TSMC's 6nm EUV process, offering a 50% reduction in power consumption compared to competitive offerings in the 12nm process. With less than 7W power consumption for the entire SSD, it delivers 1.7x better power efficiency than PCIe Gen4 SSDs and up to 70% better than current competitive PCIe Gen5 offerings on the market.

Silicon Motion will be showcasing its SM2508 based SSD design and other innovations during the Future of Memory and Storage event from Aug. 6 to 8 at booth #315: Silicon Motion's SM2508 is a superior-performance, low-power PCIe Gen5 x4 NVMe 2.0 SSD controller designed for AI-capable PC notebooks. It supports eight NAND channels with up to 3,600 MT/s per channel, delivering potential performance speeds of up to 14.5 GB/s and 13.6 GB/s and random performance speeds of up to 2.5M IOPS, providing up to 2x higher performance than PCIe Gen4 products.

The SM2508 maximizes PCIe Gen5 performance with an impressive power consumption of approximately 3W. It features Silicon Motion's proprietary 8th-generation NANDXtend technology, which includes an on-disk training algorithm designed to reduce ECC timing. This enhancement boosts performance and maximizes power efficiency while ensuring compatibility with the latest 3D TLC/QLC NAND technologies, enabling higher data density and meeting the evolving demands of next-generation AI PCs.

The SM2508 is being designed by multiple major SSD vendors including major NAND vendors. Production ramp of SM2508 is targeted for fourth quarter of this year.
