USB drives are a popular storage device today. However, USB drives are not identical and compliant. For example, USB 2.0 vs. 3.0 has different speed differences. At the same time, the market is flooded with counterfeit USBs, which suffer from poor quality, false "large capacity," and slow speeds. Here's what a Link manager reported from analyzing counterfeit USBs:

It was found that some USB drives were sold with half or even 1/4 of the actual storage capacity claimed. The firmware inside the drive was modified. In addition, counterfeit USBs would take too long (1 to 7 hours) to "pretend" to write when no data was actually written. - from Linkedin

Fake USBs can severely impact USB performance. A USB read speed can transfer data from a single 1GB file in 50 to 180 seconds of write time. You should get a professional USB speed test tool to see the exact USB read and write speed. EaseUS lists the 10 best USB benchmark tools and detailed information.
