Hi folks — I’m trying to decide whether I want to drop $300+ on an external Thunderbolt SSD. I’m driving a 2018 Mac mini with 500GB internal storage, and 1) I keep running into capacity issues, and 2) I’m a little leery of installing Big Sur on my work machine, even once the final release is available. So I’d like to get an external SSD that I can use as a boot drive, but I wasn’t aware until this morning how much more I’d have to pay for the Thunderbolt interface. Any thoughts?
