Our Take

We benchmarked 6 drives to find the fastest fastest usb-c portable ssds. The Sabrent Rocket Nano V2 tops the charts at 3.0 GB/s.

Benchmark Results

Interface bandwidth determines the theoretical ceiling, but real-world speed depends on controller efficiency, thermal management, and NAND quality. The Sabrent Rocket Nano V2 achieves 3.0 GB/s reads and 2.8 GB/s writes over USB4 — enough for direct 4K/8K video editing, massive file transfers, and demanding creative workflows.

A 40 Gbps host port is non-negotiable for Thunderbolt/USB4 drives. Without it, you are paying for bandwidth you cannot use.

Full throughput requires a Thunderbolt 4 or USB4 port capable of 40 Gbps. On USB 3.2 Gen 2 hosts, expect Gen 2 speeds — roughly 10 Gbps.
