Speed comparison for fastest usb-c portable ssds. Corsair EX400U Portable 1TB achieves 3.3 GB/s sequential reads, with 1 other drives within striking distance.
Raw sequential numbers tell only part of the story. The Corsair EX400U Portable 1TB delivers 3.3 GB/s reads over USB4, but sustained throughput under heavy loads depends on thermal design and controller firmware. Per corroborated third-party benchmarks, it maintains 3.0 GB/s+ during extended writes.
At these speeds, thermal management becomes a bottleneck. Sustained transfers can push controller temperatures past 70°C, triggering throttling that drops throughput by 30-40%. Look for drives with aluminum enclosures or thermal pads.
Thunderbolt and USB4 drives require a 40 Gbps host port. Standard USB-C ports max out at 10 Gbps, so check your machine's port specs before buying.
Multi-terabyte SSDs carry a significant premium. If your workflow demands fast access to large datasets, the investment pays off. For archival use, consider pairing a smaller SSD with a larger HDD.
| Drive | Read Speed | Write Speed | Interface |
|---|---|---|---|
| Corsair EX400U Portable 1TB | 3.3 GB/s read | 3.0 GB/s write | USB4 |
| SSK PM510 USB4 Portable 1TB | 3.2 GB/s read | 2.8 GB/s write | USB4 |
| Sabrent Rocket Nano V2 | 3.0 GB/s read | 2.8 GB/s write | USB4 |
| Samsung T9 Portable SSD | 2.0 GB/s read | 1.9 GB/s write | USB 3.2 Gen 2x2 |
| SanDisk Extreme Pro Portable SSD | 2.0 GB/s read | 2.0 GB/s write | USB 3.2 Gen 2x2 |
Without a 40 Gbps host port you will not hit rated speeds. Check your laptop or desktop specs before buying — many USB-C ports top out at 10 or 20 Gbps.
