Do I have Usb 3.0?

I have windows 10 and in device manager under usb it says Asmedia usb3.0 extensible host controller. I used flashbench to test an external usb hard drive on several usb ports. Each time it gives the read and write speeds at 35 mb/sec.

What would I need to do to get usb 3.0 speed?

Clarification Request
Need to know more.

Lower case mb? m is usually milli but OK, we are talking computers so I'll correct that the M or millions.

The b is bits but 30 megabits a second would be slow indeed. Maybe you meant B for Bytes?

The USB HDD can get slow where there are drive issues. You'll see this on surface problems, or the drive will disconnect without notice or lockup the PC.

Tell more.

I was using the wrong port

I feel really stupid and am sorry for wasting everyone's time. I have a desktop with 6 ports on the back. I never noticed until now imprinted on the silver that 2 say usb 3. I ran the benchmark and now it's 150 MB/sec.

Thanks for all your help Happy

Use the rear USB ports

Also consider the flashdrive may actually be that slow. Did you buy it from EBay?

It was actually MB

and the drive is Seagate bought from Microcenter. I did try several of the rear ports with the same result. I tried the drive on another pc using the same backup program Shadowprotect and was getting speeds over 100 MB/sec.

As these drives fill, speed decreases. Speed testing

Is done on the empty drive.

stats on speed

It looks like

You used one tool to measure speed on the original machine and then a different tool on the 2nd machine.

If that's correct try using the same tool on both.
