I feel like this is a good place to ask...

I'm looking at father's day gifts and had the idea to buy some external storage for my dad (he's an amateur photographer). I was thinking that a setup with RAID 1 would be great for peace of mind but damn they're kind of expensive. Is it worth it? I've got a couple of extra 1TB drives laying around, can I just buy one of these RAID enclosures and stick them in there?

Or is this a silly thing to worry about and should I just buy a 4TB external and call it a day?
