Crucial X8
Score: 81/100
SanDisk Extreme
Score: 88/100Rankings

The SanDisk Extreme Portable SSD 1TB provides fast 1050 MB/s reads, IP65 protection and a lightweight, bus-powered design. Its speed is modest compared with newer 2 000 MB/s drives and it only comes in a single capacity. Ideal for creators who need a portable, rugged SSD at a reasonable price.

The Crucial X8 2TB delivers solid 1050 MB/s performance in a rugged, IP67-rated aluminum case with useful adapters. Its heavier weight, lack of disclosed endurance data, and USB 3.2 Gen 2x1 bandwidth limit make it less ideal for users seeking the lightest or most future-proof drive. Suited for creators and travelers who need durable, fast storage and appreciate the included adapters.
