The Samsung Portable SSD P9 is the company’s first USB4 portable drive, rated at 4,000MB/s read and 3,800MB/s write. That’s double the T9 it sits above. It ships in 1TB, 2TB, 4TB, and 8TB capacities; the 8TB is Samsung’s first USB4 portable SSD at that size, and the 2TB unit we tested sells for $649.99
