I have a sandisk ultraluxe 128 GB thumbdrive and the transfer rate is slow.
When copying a 400mb file the transfer rate is about 1 to 2MB/s. sometimes it even drop to 0.
The thumbdrive is connected to a USB 3.0 hub.
I have tried copying the same file to a Segate external HDD connected to the same USB 3 hub and the transfer rate is more than 50MB/s.
Can anybody tell me what went wrong?
