Lexar SL100 Pro 1TB vs Crucial X10 Pro 2TB

Compare Lexar SL100 Pro 1TB and Crucial X10 Pro 2TB side by side. Both are 1TB USB 3.2 Gen 2 external SSDs, but they differ in speed, design, and value. Here's how they stack up.

Lexar

Lexar SL100 Pro 1TB
7.5/10

A 950 MB/s Gen 2 portable in a brushed-aluminum case the size of a credit card. The SL100 Pro is one of the smallest 1TB Gen 2 SSDs at retail — buy it for the form factor, not the rated speed (which undershoots the Gen 2 ceiling).

Our Pick

Crucial

Crucial X10 Pro 2TB
9.5/10

The 2TB X10 Pro takes advantage of Gen 2x2 hosts but falls back gracefully on Gen 2 to 10 Gbps. A safe long-horizon buy — even if your current laptop only has Gen 2, you'll see 2000 MB/s the day you upgrade to a Gen 2x2 host. Same TLC NAND, 5-year warranty, and encryption as the X9 Pro.
