I have 250 GB internal SSD on 2013 iMac 27''. Since that's not even close to being enough storage for me, I have multiple external HDDs for storage. Right now, my Lightroom catalog file and the photos from the library all reside in the external HDD. Would I benefit from moving my library catalog file to the SSD or should I keep them on the HDD? If so, what would be the best way for me to move without messing up the catalog(i.e. breaking the links between the catalog and photos)?
