Score: 81/100
Transcend ESD270C 250GB
Score: 68/100Rankings
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 ESD270 250 GB offers a pocket-sized form factor, solid 520 MB/s read speeds and built-in 256-bit AES hardware encryption, making it ideal for users who prioritize security and portability over raw performance. Its slower write speeds and lack of wireless features keep it from being a flagship performer.
