Score: 81/100Buffalo SSD-SAO2.0U3B
Score: 90/100Rankings
A rugged, stick-form factor 2 TB SSD designed for PS5/PS4 gamers. It delivers up to 600 MB/s via USB 3.2 Gen 2, offers AES-256 encryption and IP55 protection, but is limited to a USB-A interface and can warm under heavy use.

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.
