Btrfs' RAID1 works bit differently. It ensures every block (1GB by default I believe) is present on two devices. So, if for example, you have 2x 1TB and 1x 2TB

Btrfs' RAID1 works bit differently. It ensures every block (1GB by default I believe) is present on two devices. So, if for example, you have 2x 1TB and 1x 2TB drive, you get 2 TB of usable space.
It is arguably not the most useful property in enterprise setting, but helps to stay on budget on home projects, since I can just use random drives laying around without any further requirements on the matching of the sizes.
