Considering moving from old MBP to the new Imac. I currently have 320GB of photos in the cloud and on external HD, but I would like to store locally (not optimaized) on new iMac. Should I then consider a 1Tb or 2 Tb imac model? Or what other options would you suggest? Keep on external HD (but I want my default Photos library to be either the cloud or local imac folder so I dont have to always plug in EHD to view photos)? Thanks
