Lexar

Lexar SL100 Pro 2TB

7.6/10

The 2TB SL100 Pro keeps the same brushed-aluminum credit-card footprint of the 1TB — famously pocketable but only marginally faster on sustained writes thanks to the larger SLC cache.

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.
