First, that is normal for a startup volume due to the "busy" nature of macOS. You've never noticed it because the Mac does not have a drive activity indicator. Second, be sure to use the best settings in Energy Saver to prevent the external drive from going to sleep when the computer is asleep. Here are the settings I use.

If I'm not mistaken all Ugreen enclosures have a setting that will put the drive to sleep after several minutes of inactivity regardless what the settings are in the Energy saver pane.

Hi tbirdvet,

That is what stated by Ugreen, however for some reason that feature does not work.
