Score: 84/100Rankings

The Samsung Type-C 512 GB flash drive offers fast 400 MB/s read performance in a compact metal chassis with a reversible USB-C connector and five-proof ruggedness, backed by a 5-year warranty. Its write speed is modest and the capless design may attract debris, but it excels for modern USB-C devices and demanding portable use.

The PNY 512GB Turbo Attaché 3 offers high capacity and decent read speeds in a capless sliding design, but its bulky plastic body and lack of encryption limit its suitability for security-focused or ultra-compact needs.
