Pocket Portable SSDs
Our pick
Lexar SL500 1TB
Choose the Lexar SL500 1TB for a pocket SSD you carry with a laptop.1
Why this one
- At 43g and 7.8mm thick, it adds less weight and bulk than the 122g, 14mm Samsung T9 2TB.12
- Its read rating reaches 2,000 MB/s over USB 3.2 Gen2x2 for large-file transfers on a host that supports that interface.1
- Lexar provides five years of warranty cover, compared with three years for the Corsair EX400U.13
The alternatives
Other contenders
Choose the Corsair EX400U 2TB for a USB4 host, with advertised peaks up to 4,000 MB/s read and 3,500 MB/s write. Compare long-transfer tests if sustained copying is your main use.4
Choose the Lexar SL600 4TB when you need a larger working library on a USB 3.2 Gen2x2 host, with the same five-year warranty term as the SL500.15 Its 64g, 10.6mm body is larger than the SL500 1TB’s 43g, 7.8mm body, so choose it for the extra capacity rather than the smallest carry size.15
Choose the Samsung T9 Portable SSD 2TB instead when you want a stated drop rating of up to 3m.2
For laptops with USB4
Use a matching USB4 host for these rated transfer peaks, and check tests with your computer when long copies are the priority.4 Choose the Corsair EX400U 2TB for rated reads up to 4,000 MB/s and writes up to 3,500 MB/s over USB4.4
