Backup drive is my use-case. But that means a mountain of sustained write traffic, which means thermals are important, which is where this thing sucks. I had been using a regular external with a short cable, until I got a Framework and decided to try one of their "fits in the module slot" SSDs, which is perfect.

I still pop it out after the backup and store it elsewhere, but it's lovely that during the backup job (which can take a while if it's doing a fresh copy), it's completely unobtrusive and can't break off if I set the lappy down wrong.
