Samsung adds USB4 P9 and P7 portable SSDs

Samsung unveiled its P9 and P7 portable SSDs on 26 August at Gamescom. Both use USB4. Samsung rates the flagship P9 for sequential reads up to 4,000MB/s and writes up to 3,800MB/s, and calls its 8TB version the first USB4 portable SSD at that capacity and speed. The P7 is positioned for everyday use and is rated for up to 2 metres of drop resistance.

The P9’s claimed throughput depends on a compatible USB4 host and cable; it will not reach those rates through every USB-C connection. Samsung said global availability would begin in September, with capacities and prices varying by model. Those are manufacturer specifications, not independent sustained-transfer tests.
