hi

any body know the reason or if there is any way to fix or improve this behavior
the writing to the USB is always looks like a sin wave and the speed is fluctuating as you can see in this picture

copy from the main hard drive to the USB drive on USB 2.0 Port , the issue here not max speed as the max speed in my case is Ok for USB 2.0 but the issue is the sin wave performance is down to 300KB
i have tested different ports on PC.

i also see the same effect when connected it to USB 3.1 Gen 1 port on laptop the sin wave is still there but the min and max speed is higher because of USB 3.1.

the main reason i have asked to know is this normal for all devices with same model and prand
o i just got a defected one.
