Hello, all. I'm interested in updating my 2009 Mac Mini to the new, entry-level version, but I have some questions about external storage. I currently have a 1TB hybrid drive, mostly to house my photo collection. I know I can offload the Photos.app library to external storage (TB/USB3) on the new Mini and just use the internal 128GB SSD for system files, etc. But... 1. Does the external drive need to be SSD if it's just for accessing photos? Not editing or doing video work, just a place to park the Photos library. A platter HD would be much less expensive, and I would just make sure to buy a modern one with a fast interface, correct? 2. If I want to back up the external drive to have a backup of my photos, can I just do that by connecting another drive to the Mini and running CarbonCopyCloner or something similar? Thanks in advance for the help!
