The Hopper 3 has a 2TB internal hard drive, so you should not have to worry about running out of available space as quickly as you might on the ViP612.
You'd be surprised, my external drive is a 2TB drive. I've recently done some pruning of recordings and it is still over 3/4 full.
I seem to recall that you can swap out multiple external drives. True? Any cautions?
Looks like I'll pull the trigger early next week. Just detailed all my scheduled recordings to a spreadsheet. Next will be my searches.
Finally, I will review my settings. Can't even remember which one's I made. Any recommendations or new ones that will come with the Hopper 3?
