copy and paste, deleting files etc slow

Is there any reason why copying and pasting between USB drives on windows 7 professional is slow pathetically slow? I have a reasonable spec laptop, but even deleting files is taking an age. And copying and pasting between the internal HDD and external USB is taking literally hours for only a few GB of data. Downloading large files from the Internet has no issue at all. I dont get why the speed issues are as such? Any potential theories to investigate further.

1) Are the USB drives almost full?
2) Are they attached to different USB ports?  (they should be)
3)  Are the USB drives up to date.  Check in Device Manager.  Or, in Device Manager, uninstall the USB drives (not delete) and reboot.  Windows should install latest drivers.
4)  Have you tested the USB drives on a different PC to see if they perform any better?
5)  Run a virus and malware scan.

Since the USB drives work on other PC's, the problem is with the PC you are working on.  Have you tested Memory?

Yes but the drivers governing USB performance may not be!
