Ranked #4 in Best External SSDs

Crucial X10 Pro

4.2

1 source$194.99as of Oct 11

The SSD Review and StorageReview both frame the Crucial X10 Pro as a high-performance portable drive for media professionals, moving data over USB 3.2 Gen 2x2. They praise the ultra-compact aluminum build and the security package, hardware encryption plus a 5-year warranty, that separates it from the base X10. Some testers saw sustained write performance dip below Crucial's maximum claims under heavy loads. Get it if you have a compatible 20Gbps port and value speed and durability over cost; on older USB ports the slower, cheaper X9 Pro makes more sense.

Strengths

— Supports USB 3.2 Gen 2x2 interface for up to 20Gbps transfer speeds
— Compact 65 x 50mm unibody anodized aluminum chassis weighing 1.48 ounces
— Includes 256-bit AES hardware encryption with software-based password protection

Watch-outs

— Higher price point compared to standard USB 3.2 Gen 2 portable SSDs
