"adheres to USB 3.0 standards for data transfer speeds of up to 5 Gb/s", Yes that is the standard for 3.0 transfer. Many flash drives are the same standard but their write speeds are much, much less. What are the actual read and write speeds?
Asked by: James
Actual transfer rate depends on a variety of factors and can vary dramatically.
