I want to make a NAS with a 500GB boot drive and 2x16TB HDDs. Based on my previous post, btrfs is a good option. It also looks easy to get started. My plan for the NAS would be to purchase several 16TB drives, and only use 2 of them.

My first question is about different drives. Could I purchase two different brand drives and use them with btrfs? (I assume yes)

2nd question: how does the replacement process go? Like if drive A died, so I remove it, and put a brand new replacement in. What do I have to do with btrfs to get the raid 1 back going? Any links or guides would be amazing.

I'm using Synology/DMS and there you have a pretty neat GUI that lists newly detected drives and let's you assign them to your storage pool and rebuild the raid. I'd expect it to be quite similar on software like TrueNAS Rockstor.
