Buffalo SSD-PUT500U3B
Score: 81/100
Transcend Portable SSD 500GB
Score: 57/100Rankings
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 Transcend 500 GB portable SSD offers fast 1050 MB/s reads, a feather-light aluminum body and full-disk AES-256 encryption, making it ideal for creators on the go. It includes versatile cables but may warm up and the case feels cheap.
