I want to benchmark a USB host on my custom machine. It has Busybox V1.20.2. From google, I see that it can be done using dd command.

For testing, i copy blender.exe (76MB) to the home folder in machine. Then I plug in USB thumbdrive, mounted it at /mnt, then I typed:

dd if=/home/blender.exe of=/mnt/blender.exe bs=64k count=1024

The operation works but at the end there is no indication of speed transfer report. It just shows:

1024+0 records in
1024+0 records out

I checked the file has been copied successfully into thumbdrive. I suspect that it is the version of dd boxed into the busybox that is old one.

Is there any other way to check the transfer speed?

Use the time command to measure how long the transfer took, then use a calculator to calculate the transfer rate.
