Score: 81/100Rankings

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.

Buffalo's 1 TB SSD-PUT is a thumb-drive-sized external SSD that delivers solid 600 MB/s read performance in a rugged, MIL-STD-810G package, though it needs a firmware update and uses an adapter for USB-C connectivity.
