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.

It is better to have more drives and less apares. However, btrfs is only stable in raid 1. With data that big I would go ZFS raidz2 as you can lose up to 2 drives.
From a btrfs perspective it is pretty easy as you just can run btrfs replace with the path of the new drive. Btrfs also has the benefit of being native
BTRFS is stable for all RAID levels except for RAID 5 and 6 (because of the write hole). I'm using it with RAID 10.
