Score: 81/100
SSK Portable SSD 256GB
Score: 53/100Rankings
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 SSK 256 GB Portable SSD delivers fast USB 3.2 Gen 2 performance in a lightweight aluminum enclosure, with broad compatibility but limited capacity and no built-in encryption.
