The system probably isn't configured to boot from the USB 3.0 ports. Can you disable booting from the USB 2.0 ports (assuming that the delay is caused because the system tries to boot from a USB device)?
Thank you for your response. I'm a noob at this stuff, but I did find the boot options and disabled every boot option but my SSD and my CD/DVD Drive (currently it had a printer?? and 3 externals listed in the boot options).
My boot order is SSD > CD/DVD Drive.
Disabling all other boot options shaved the time down form 30s to about 20s, but still is a much larger value than when I don't have my 3 external HDDs plugged in.
