Can I eject the fast drive from Finder instead of from Storage Studio?
Short answer: Yes, it's safe — Storage Studio notices and pauses drive work. Its own Eject fast drive is more thorough: it pauses automatic actions, asks apps using the drive to quit, and names anything still holding files.
You can, and nothing breaks — Storage Studio notices the drive has gone and pauses the work that needs it. Its own Eject fast drive is a little more thorough, though: it pauses automatic actions first so nothing starts mid-eject, asks apps that commonly use the drive to quit, and if the eject fails it tells you which apps are still holding files.
If Finder says the disk can't be ejected because it's in use, try Storage Studio's eject to see what's holding it.
