Intended for AI PCs and gaming consoles, it’s the world’s first PCIe Gen5 client SSD controller that uses TSMC’s 6nm EUV process, offering a 50% reduction in power consumption compared to other 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's SM2508 supports eight NAND channels with up to 3,600 MT/s per channel, delivering sequential 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 device maximises PCIe Gen5 performance with a 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 and boosts performance and maximises power efficiency while ensuring compatibility with the latest 3D TLC/QLC NAND technologies. This enables higher data density and meets the evolving demands of next-generation AI PCs.
“SSD storage solutions are continuously evolving to meet the new challenges posed by future AI applications, which demand data efficiency and high-performance models,” said Nelson Duann, Silicon Motion’s Senior VP of Client & Automotive Storage Business. “Our PCIe Gen5 SSD controller, with its best-in-class power efficiency, is designed to satisfy the unique demands of today’s AI-capable PCs, delivering high performance and power efficiency to meet the evolving AI PC standards of tomorrow.”
The SM2508 specifications include:
- PCIe Gen5 x4, NVMe2.0
- 8 NAND flash channels, up to 3600MT/s
- TSMC’s 6nm process
