I just added a USB 3.1 SSD drive to my iMac for my less-used files (like videos and older RAW photos) and download archives. I also have a USB 3.0 spinning drive that I already use as my Time Machine. My questions are, can I backup both my iMac's internal drive and my external SSD drive to the same Time Machine drive, and if so, how does that look on the Time Machine drive itself? If I need to restore my iMac, how would that affect the SSD? Could I restore my iMac without needing to restore the SSD, or would that mess up the whole process?
