If you can't store the data you can't do the task. It doesn't matter how fast your storage is if you can't fit the required files. That's bad performance. Additionally then they have to load over USB3 external HDD or network storage (which is probably over wifi!) and that's awkward and slow in both the physical and digital sense. My experience is based mostly off doing IT support for mostly non-technical family and friends. By backups I meant OS features that do system file restorations from checkpoints like common in Windows and Apple. It is also common to have these on the same computer. Even if they're stored externally the computer running time machine must have that much local space free. So many of my tech support visits are helping people who run out out the tiny disk space on their affordable model Apple laptops and are no longer able to make time machine back-ups to their external HDD storage till they free the required space. People commonly run out of 250 GB storage without even doing data intensive hobbies. I don't think my experience is unique.
