UserBenchmark

Speed test your USB in less than a minute.

We highlight the best USB flash drive in terms of balanced performance and value for money using current prices, sequential read, sequential write , 4k read and 4k write speed. The speeds are combined to form a single effective speed which measures performance for tasks such as copying photos, music and videos. Effective speed is adjusted by current price and capacity to yield value for money. Finally thousands of individual user ratings are used to validate our benchmark figures.[USBFlashPro]
