How to choose
Choose USB4 drives like the Corsair EX400U (4,000 MB/s) if you transfer large video files; choose USB 3.2 Gen 2x2 drives like the Samsung T9 (2,000 MB/s) for balanced speed and price.
For harsh environments, select the LaCie Rugged SSD with its IP67 rating and 3m drop rating; for general use, the Crucial X9 Pro’s IP55 rating and 7.5ft drop rating are sufficient.
If you need over 4TB, the WD My Passport offers up to 6TB capacity but sacrifices speed; for faster transfers, stick to SSDs with capacities typically capped at 2TB or 4TB.
Ensure your computer has a USB 3.2 Gen 2x2 port to get full speeds from the Samsung T9 or Kingston XS2000; otherwise, the Crucial X9 Pro offers consistent performance on older ports.
Our verdict
The Samsung T9 is the best overall portable SSD external hard drive for most users due to its 2,000 MB/s speed and $110 price point, while the Crucial X9 Pro offers the best value for durability-focused buyers.
