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?
