Review summary
Written by Augur from the 6 reviews analyzed
This 256 GB flash drive stands out with its compact and colorful design, created for daily file storage and transfer. It is designed to be extremely simple to use, offering a practical and affordable backup solution for large documents.… However, its performance remains very modest with a maximum read speed of 30 MB/s and a write speed limited to 10 MB/s, which will slow down the transfer of very heavy files.
