USB 3.0 Drive Speeds

What are you copying?  Small files of a few KB to a couple MB will copy much slower than a large ISO or video file.

You may also need to upgrade your computer's USB3 drivers.

And your hard drive might be old, failing, full, fragmented, slow, or busy doing other things.

lots of small files, the drives are brand new.

Are the appropriate USB 3.0 drivers correctly installed?

I believe so, looking at HP website now.

Sorry, but lots of small files just take longer.  The file has to be found, opened, read, read, closed, Instead of found, opened, read, read, read, read, read, read, read, etc, closed.

I'd suggest using USB Device Tree Viewer to determine what type of USB connection is actually being established with the device (ie "High-Speed" or "SuperSpeed").

Select the device you're concerned with and examine the Connection Information to that appears in the right pane.

Devices connected in USB 3.0 "SuperSpeed" mode will report:
Device Bus Speed         : 0x03 (SuperSpeed)

Devices using USB 2.0 will show:
Device Bus Speed         : 0x02 (High-Speed)

I have the latest and greatest

You shouldnt expect a very high speed on USB3.0 by copying lots of small files as noted above. There are plenty of small operations which steal your speed.

Thanks guys, I guess it is what it is.  I did download and install USB tree Viewer.
