Hey guys, I need help! I use Lightroom to batch edit photos. Im running a year old 5k Mac Desktop with a 1 tb hard drive and it's pretty much maxed out. I do however store all of my raw images and my Lightroom Catalog on my 4TB Seagate external hard drive because I shoot so much my computer would otherwise fill up. My Lightroom seems to bog down when editing.. When I batch edit a group of photos or do to much stuff at once Lightroom will slow down and make things take much longer. Is this because my catalog and photos are on my external drive? Does anyone use Lightroom and has ever had issues similar to this?
