KingSpec XG7000 1TB M.2 2242 NVMe PCIe SSD Gen 4x4 4.0 (works in Legion Go etc.)

This is a very capable and highly regarded SSD, with read speeds up to I believe 7200MB/s and write speeds up to 6400MB/s (YMMV).

This product would be ideal for users who require high-speed SSD storage for their gaming laptop, compatible with software like DOOM Eternal and Hitman 2.
