Score: 76/100Rankings

The Samsung X5 is a Thunderbolt 3-only, NVMe-based portable SSD delivering flagship-class speeds in a rugged magnesium case. It targets professionals who need ultra-fast transfers and built-in security, but its lack of USB compatibility and higher weight limit its appeal to casual users.

The Samsung T5 1 TB Portable SSD delivers reliable 540 MB/s read speeds, solid aluminum construction, and built-in 256-bit AES encryption. It remains a benchmark for portable SSDs despite its modest capacity options and lack of an endurance rating.
