The subject line says it all. If you have a newer imac with Catalina/APFS and want to create a bootable backup volume on a non-SSD drive with Carbon Copy Cloner. . I have an internal 2TB SSD drive and just need an external drive for extra storage for the files that don't see much if anything and a bootable backup clone in case something happens. So I don't need an external SSD drive, and given the cost of a 4TB SSD, the Novus 4TB drive was a very affordable option and met my needs.
