Yes, it Grows and Grows... but it's worth it..
I've Got Two 5TB drives now, and an Older 4TB drive.
All mostly dedicated to iStripper.
One as my Daily use drive, and the other two as my backups.
Always have a 2nd drive with backups of your Collection. One day you will be glad you have it..
I don't keep it updated daily, once a week, Twice a month...
I'll update the Backups to keep them up to date...
I don't mind having to re-download a handful of cards, but I wouldn't want to re-download my Entire Collection.
