I am about to start using Lightroom 5 to edit a large amount of photos, it will be between 100-200gb RAW files, ideally I'll be editing and exporting in batches of a few hundreds at a time (the edits will mainly just small alterations, nothing too heavy). I currently have an SSD in my Mac which does not have the space for this amount of photos (and my other stuff). Is Lightroom useable with an external USB drive? The drive is a 7200rpm, 1tb drve (2.5" drive in enclosure). My Macbok pro is a 2012 model with 16gb RAM and 2.3ghz i7 processor.
Thanks for any tips
Should not be a problem.
