Score: 81/100
Lexar ES3 1TB
Score: 70/100Rankings

The Buffalo 500 GB SSD-PUT combines ultra-compact pen-drive dimensions with fast NVMe-over-UASP performance, but its modest PCMark score and lack of a native USB-C port keep it from being a premium choice.

The Lexar ES3 1TB SSD offers ultra-fast USB-C performance in a lightweight metal shell, with software-based 256-bit AES encryption and extensive device compatibility. Its main drawbacks are limited iPhone support and the need to install encryption software.
