Crucial X8 1TB
Score: 71/100
Buffalo SSD-PUT500U3B
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.
The Crucial X8 1TB Portable SSD offers NVMe-class speeds and a rugged aluminum body at a competitive price, but lacks encryption and sees write performance dip after the cache is used.
