Question: Do USB hard drives slow down Mac Pro?
I have an early 2009 Mac Pro and use it for photo/video editing. It works fine but I notices that sometimes it takes a lot to open up the "save as" window or to do some very basic functions. I have a few HDs connected via USB and wonder if that could be a drawback in the Mac's performance.
Thanks in advance,
Mac Pro, iOS 10.1.1
