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

Samsung T7 Shield

4.4

4 sources

Reviewers rate the Samsung T7 Shield mainly on toughness: IP65 water and dust resistance plus 3-meter drop protection make it a reliable travel and outdoor drive. They also point to AES 256-bit hardware encryption and a 4TB capacity that is rare in Samsung's portable lineup. The soft silicone exterior attracts dust, and the top transfer speed of 1050MB/s only arrives if the host supports 10Gbps USB. Pick it when durability and security matter more than sleek looks or peak speed on older hardware.

Strengths

— IP65-certified water and dust resistance
— 3-meter drop resistance for durability
— AES 256-bit hardware encryption for data security

Watch-outs

— Silicone exterior casing attracts dust and lint
— Requires 10Gbps USB port for maximum 1050MB/s speeds
