Crucial X8
Score: 81/100
SanDisk Extreme PRO
Score: 91/100Rankings

The SanDisk Extreme PRO 1TB Portable SSD provides flagship-level 2000 MB/s read and write speeds, IP65 water-dust protection, and 128-bit AES encryption for professional creators. Its premium price and lack of bundled software may deter casual users.

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.
